the battlefield In order to accomplish this nations indigenously develop maintain and improve a variety of ground combat systems or purchase them from other nations Ground combat system development and improvement is informed by existing and emerging technologies and budgetary factors as well as observations from current land conflicts As this process is also intended to address potential future battlefield threats beliefs as to what the future combat operational environment will look like as well as what future technologies might be available for military use also influence a nation’s developmental efforts The U S Army’s current fleet of main battle tanks MBTs tracked infantry fighting vehicles IFVs tracked self-propelled SP artillery and multiple launch rocket systems MLRS which constitutes the nucleus of the Army’s armored ground forces were developed in the 1970s and fielded in the 1980s to counter the Soviet Union’s and Warsaw Pact’s numerically superior ground forces The combat performance of these vehicles against Iraqi forces during Operation Desert Storm in 1991 reaffirmed for many the role these systems would play in future Army ground operations U S Army leadership notes for the first time since World War I that the Army does not have a new ground combat vehicle under development and “at current funding levels the Bradley and Abrams will remain in the inventory for 50 to 70 more years ” Regarding armored vehicle development the Army suggests “our enemies and even our friends and allies have not remained static and in fact even our allies are modernizing to such an extent that they have outpaced us in some areas ” This comment raises the possibility that in the not-too-distant future foreign armored vehicle design and capabilities could surpass existing U S systems Observations from current conflicts as well beliefs as to what future conflicts might look like help determine what types of improvements should be made to existing combat vehicles in terms of lethality survivability mobility and maintainability They may also lead to a conclusion that an entirely new combat vehicle will be required to address current and potential future threats Comparison of selected U S and foreign ground combat systems and observations from current conflicts as well beliefs as to what future conflicts might look like raise implications for U S ground combat system modernization Some of these implications include the following     the possibility U S ground combat systems could be outpaced by foreign systems that increasingly capable foreign ground combat systems could be an option for acquisition the reemergence of air attack artillery and electronic warfare EW as ground combat system modernization concerns and the consideration of system level issues such as  Forward Looking Infrared Radar FLIR and Fire Control Systems FCS  Active Protection Systems APS  new and Cluster Munitions Ban-compliant artillery rounds and rocket

Important to Congress Article I Section 8 of the Constitution charges Congress to “raise and support armies ” On an annual basis Congress authorizes and appropriates funds for the Army to among other things modernize its fleet of ground combat systems As part of this process congressional defense committees annually hold dedicated hearings on the Army’s Budget Request for the upcoming fiscal year

Systems Modernization The U S Army’s current fleet of main battle tanks MBTs tracked infantry fighting vehicles IFVs tracked self-propelled SP artillery and multiple launch rocket systems MLRS the nucleus of the Army’s armored ground forces was developed in the 1970s and fielded in the 1980s to counter the Soviet Union’s and Warsaw Pact’s numerically superior ground forces The combat performance of these systems against Iraqi forces Operation Desert Storm in 1991 reaffirmed for many the role these systems would play in future Army ground operations Efforts to modernize these systems however did not enjoy the same level of success as did their 1991 combat performance In 2002 the Secretary of Defense cancelled the $11 billion Crusader SP artillery system largely due to its excessive weight and cost In 2009 the Secretary of Defense cancelled the $160 billion Future Combat System FCS program intended to develop replacements for the M-1 Abrams tank the M-2 Bradley IFV and the M-109A6 Paladin SP artillery system due to unrealistic technology expectations and cost A spin off modernization effort to replace the M-2 Bradley the Ground Combat Vehicle GCV was cancelled in 2014 due to affordability concerns In light of these and other program cancellations the 2011 Decker–Wagner Army Acquisition Review1 found that since 1996 the Army had spent over $1 billion a year on programs that were 1 The 2011 Decker–Wagner Army Acquisition Review was an Army acquisition review chartered by then Secretary of the Army John McHugh to look into the Army’s acquisition processes The

of U S Army Ground Combat Systems ultimately canceled and since 2004 that amount had increased to between $3 3 billion and $3 8 billion dollars a year This amount represented 35 to 42 percent of the Army’s research development testing and evaluation RDT E budget 2 This report commissioned by Army leadership further served to erode confidence among some policymakers that the Army could successfully modernize its major combat systems This perception along with significant budgetary restrictions has created a dilemma for the Army Army leadership notes for the first time since World War I that the Army does not have a new ground combat vehicle under development and “at current funding levels the Bradley and Abrams will remain in the inventory for 50 to 70 more years ”3 Regarding armored vehicle development the Army suggests “our enemies and even our friends and allies have not remained static and in fact even our allies are modernizing to such an extent that they have outpaced us in some areas ”4 raising the possibility that in the not- too-distant future foreign armored vehicle design and capabilities could surpass existing U S systems The Army’s effort to replace the Abrams and Bradley referred to as the Next Generation Combat Vehicle NGCV is reportedly anticipated to be A multi-decade effort that will require completing the majority of the work prior to 2025 because it’s going to take 10 years for industry to actually build and field what we want for the first unit equipped in 2035 Tied in with the initiative will be four years of analysis and a focused science and technology effort 5 This approach suggests that for almost the next two decades the Army will continue to rely on legacy upgraded Cold War ground combat systems In the meantime other nations could potentially develop and field multiple iterations of new advanced ground combat systems while a number of factors including limited funding and the constraints of the U S defense acquisition process precludes similar U S developmental efforts One defense expert characterizes the U S defense acquisition process as consisting of a ponderous requirements definition process ill-informed by knowledge resident in the defense industrial community engage in an excessively drawn out series of competitions and then pursue a painfully laborious major program that might produce half of what is needed in twice the time and at higher costs 6 This situation is further exacerbated by what some consider a less than well-defined vision for the NGVC That’s not to say that the next-generation combat vehicle might be an infantry fighting vehicle But it could also be a single combat vehicle that replaces the Abrams and the Lou Wagner the now retired former chief of the Army

Note See the Appendix for table-related terms and abbreviations CRS-7 Selected Foreign Counterparts of U S Army Ground Combat Systems General Comparative Observations The following sections provide general observations based on a comparison of the aforementioned systems It is not intended to be a definitive technical evaluation of these systems but instead provide context for current and future policy-related discussions Main Battle Tanks MBTs 8 Many tank-producing countries have given protection priority over lethality or mobility particularly the United States and Israel This emphasis is largely in response to the proliferation of precision anti-armor weapons including both direct and indirect fire weapons as well as improvised explosive devices IEDs Many foreign tanks have incorporated an automatic loader for their main gun replacing one of the crew members thereby permitting a smaller design and resulting in a potentially lighter vehicle The autoloader also facilitates a greater rate of fire but puts the main gun at a greater risk of jamming than would a manual loader While there are advantages to a smaller crew they come with decreased situational awareness as well as a decreased physical ability to maintain the tank Active protection systems APS 9 are featured on a number of potential protagonists as well as allies’ tanks but the U S despite a long-standing interest in APS has yet to field an existing system or a developmental one APS is seen as a means in conjunction with vehicle armor to enhance crew survivability from an ever-growing range of threats Some tanks including the Israeli Merkava Mk 4 and reportedly the Russian T-14 Aramata10 are designed around an integral APS as opposed to having a system retrofitted to the tank which is generally considered a suboptimal solution Some Russian and Chinese tanks are also employing larger caliber main guns than their Western counterparts theoretically offering greater range and armor penetration It should be noted however that the quality and performance of main gun ammunition also plays a highly significant role in a tank’s lethality Some of the larger caliber main guns reportedly can also fire anti-tank guided missiles in addition to their traditional tank main gun rounds further enhancing lethality 11 In terms of fire control systems while once a U S comparative advantage most tanks now employ some form of Forward Looking Infrared Radar FLIR as well as Global Positioning Systems GPS and thermal and night vision technology thereby to a certain extent “leveling the playing field” with the U S M-1A2 Abrams tank Tracked Infantry Fighting Vehicles IFV 12 In a manner similar to main battle tanks the trend in IFV development is towards heavier vehicles ranging from 20 to more than 60 tons to address both the proliferation of AT systems and IEDs and a growing tendency for combat operations to occur in urban areas In the case of Information in this section unless otherwise noted

M-2A3 Bradley its weight growth over time has resulted in the loss of its original swim capability Compared with many of its foreign counterparts which mount 30 and 40 mm cannons the M2A3 Bradley’s 25 mm cannon is generally considered to be at a relative disadvantage against some armored vehicles and well-constructed buildings While the 25 mm is considered to have excellent armor penetration for the caliber some of the larger IFV cannons have both superior anti-armor capability and larger high explosive rounds In addition to cannons many tracked IFVs including the Bradley are capable of firing ATGMS either from their cannons or from separate external mounts Most countries build their tracked IFVs to carry an entire infantry squad—although squads for the countries compared range from 6 to 8 soldiers while a U S infantry squad presently consists of 9 soldiers It should be noted the M-2A3 Bradley does not accommodate an entire infantry squad and past requirements for the Bradley’s replacement have stipulated a capacity to accommodate a 9 soldier squad While having the entire squad in a single IFV is viewed by some as enhancing command and control and simplifying logistics others note the advantages of splitting a squad between two vehicles to insure some residual combat capacity should one of the squad’s two IFVs suffer a catastrophic kill A number of foreign tracked IFVs mount either hard kill13 or soft kill14 APS and the Army is presently examining both non-developmental and developmental APS options for the Bradley The Bradley’s limitations in terms of its capacity to support the added weight and power requirements of an APS as well as internal and external space constraints are generally considered limiting factors should the Army opt to adapt APS for use on the Bradley Tracked Self-Propelled SP Artillery A 2014 RAND research report notes In terms of cannons the U S Army’s Paladin self-propelled howitzer has a digitized fire control system but lacks the high level of automation that exists in top-quality foreign selfpropelled weapons such as the German PzH2000 15 In terms of lethality the report suggests Medium self-propelled howitzers that outrange Paladin while firing standard ammunition are increasingly common While Paladin can make up some of the range gap using Excalibur 16 this requires the use of an expensive round that is fielded only with a unitary warhead See below Department of Defense DOD Policy on Cluster Munitions for further explanation the disadvantage of Paladin’s shorter range while employing special ammunition types such as smoke or illumination rounds remains A quick comparison of the ability of a platoon of four Paladins and four PzH 2000s to deliver fires over a three-minute period shows the limitation of the U S system compared with the leader among the world’s self-propelled howitzers While a Paladin platoon could deliver 48 shells in an intense three-minute fire mission the German platoon could deliver

do so at distances up to 50 percent greater than Paladin’s maximum range 17 Multiple Launch Rocket Systems MLRS Regarding U S MLRS systems RAND suggests that current U S MLRS are being outranged and have limited munition options The U S Army’s Multiple Launch Rocket System MLRS and the similar High Mobility Artillery Rocket System HIMARS lack the range of some of the heavy foreign largecaliber artillery rocket systems particularly some that have been developed by China Therefore the rocket systems are falling behind the increasing range of similar Russian and Chinese rocket systems The trend of foreign heavy MLRS being able to fire well over 100 km has implications for the U S Army’s fires system including counter fire and target acquisition Although the Guided MLRS GMLRS rocket has exceptional accuracy compared with any fielded foreign system the suite of munitions available to MLRS and HIMARS is very limited compared with foreign rocket launchers A large portion of the Army’s current stock of rocket munitions will also have to be replaced when the 2019 limitations on submunitions take effect 18 See text box below for further explanation Department of Defense DOD Policy on Cluster Munitions In 2008 94 nations signed the Convention on Cluster Munitions While the United States did not sign the convention along with Russia China and Israel it did agree to address the humanitarian aspects of unexploded submunitions In June 2008 DOD issued its policy on cluster munitions with one of its central directives being the unwaiverable requirement that cluster munitions used after 2018 must leave less than 1% of unexploded submunitions on the battlefield In December 2008 the Army decided to cease procurement of the Guided Multiple Launch Rocket System GMLRS warhead and Dual-Purpose Improved Conventional Munition DPICM artillery rounds because their submunitions had a dud rate up to 5% This decision to insure compliance with DOD policy means that beginning in 2019 the Army will no longer be able to employ these missiles and artillery rounds which constituted a significant portion of stockpiles The inability to use these weapons is viewed by some as having a potentially significant operational impact Current and Future Operating Environment As previously discussed observations from current conflicts as well as beliefs as to what future conflicts might look like inform the military modernization process These observations and beliefs are used to help determine what types of improvements should be made to existing ground combat systems in terms of lethality survivability mobility and maintainability They may also prompt a conclusion that an entirely new combat system will be required to address current and potential future threats 17 John

Congressional Research Service R44741 · VERSION 4 · UPDATED 10 Selected Foreign Counterparts of U S Army Ground Combat Systems The Current Operating Environment A number of military analysts and policymakers view the 2006 Israeli conflict in Lebanon and Gaza and the ongoing conflicts in Ukraine Syria and Iraq as representative of the current operating environment These conflicts are seen as illustrative in terms of both middle and high end threats which the U S military might face in the near term or immediate future “Hybrid” Force A “hybrid” force has been defined as falling between a traditional non-state irregular force and a nation-state’s conventional armed forces Hybrid forces exhibit a degree of discipline are moderately trained and can operate up to battalion level about 500 soldiers They are equipped with more advanced small arms RPGs ATGMs mortars man-portable air defense MANPADS and longer-range rockets than irregular forces They exercise command and control by multiple means and operate in a decentralized but coordinated manner Hybrid forces often operate in complex terrain including urban and often fight “among the people” to maximize their effectiveness The 2006 Lebanon Conflict19 The 2006 conflict between Hezbollah and Israel demonstrated how a non-state irregular force could transform into a “hybrid” force if provided with advanced weaponry from other states After previous conflicts with Israel and having studied how they responded to past attacks Hezbollah evolved by acquiring more advanced RPGs ATGMs MANPADS mortars and rockets from countries such as Russia and Iran They also changed their tactics Hezbollah employed their advanced weapons from hidden positions in complex terrain over about a 27 by 27 square mile area in southern Lebanon creating a standoff threat for Israeli forces Israeli forces used to fighting unorganized minimally trained and commanded irregular forces experienced a number of difficulties Many Israeli tank crews did not know how to execute battle drills or screen their tanks from observation with smoke Many Israeli commanders also did not know how to integrate heavy mortars and machine guns to support their maneuver The combination of advanced long-ranged anti- tank and anti-aircraft weapons new Hezbollah tactics effective communications and command and control and Israeli training deficiencies resulted in significant damage and destruction of Israeli armored vehicles and served as a “wake up call” for the Israeli armed forces As a result of the 2006 conflict Israel developed and fielded the Namer IFV acquired more Merkava MkIV tanks and fielded the Trophy APS Israel also changed its doctrine and training emphasis from fighting irregular forces to fighting hybrid forces and focused its training on combined arms fire and maneuver as well as air-ground operations These and other changes were credited with improved performance and fewer Israeli casualties during combat operations in Gaza in 2014 The Ukraine Conflict Some experts believe the 2014 Ukrainian conflict reflects “a closer interaction between a state Russia and its proxy Ukrainian separatists and the use of weaponry that the United States has Information in this section unless otherwise noted is taken from David E Johnson “The Challenges of the Now and Their Implications for the U S Army ” RAND

Counterparts of U S Army Ground Combat Systems not confronted since the Cold War in theory and since the Vietnam War in practice ”20 The Army’s 2015 Combat Vehicle Modernization Strategy notes In the aftermath of its annexation of Crimea in March 2014 Russian forces began supporting separatists in Eastern Ukraine with advanced weaponry fire support and special and conventional forces This ongoing conflict offers important insights for the U S Army about the lethality of the modern battlefield lethality the U S Army has not faced since World War II Russian and separatist forces are employing combined arms warfare with advanced weapons to devastating effect Russian artillery particularly rocket launchers with conventional thermobaric and cluster munitions—using unmanned aerial systems UAS both for target location and battle damage assessment—is particularly effective against Ukrainian light armor and infantry formations Additionally the Russians are using their most advanced tanks in the Ukraine including the T-72B3 T-80 and T-90 All of these tanks have 125mm guns capable of firing a wide range of ammunition including antitank anti-helicopter missiles with a six kilometer range and advanced armor protection including active protection on some models Finally the Russian air defense systems man-portable and vehicle mounted have made it all but suicidal for the Ukrainian Air Force to provide air support to ground forces Thus the battlefields of Eastern Ukraine are similar to those envisioned by the U S Army during the Cold War but with more mature technologies It is a battlefield that requires armor for maneuver Light skinned vehicles including BMP infantry fighting vehicles have proven vulnerable to both artillery and tank fire Dismounted infantry in defensive positions risks becoming fixed by fire and either isolated or overrun by maneuvering units supported by tanks In short the Ukrainian battlefield is a harbinger of the complex environment the U S Army will face in the future a battlefield that requires mobile protected firepower the integration of all arms and counters to long-range artillery UAS air defenses and tank protection systems 21 Other observations from the Ukrainian conflict emphasized Russia’s “heavy and integrated” use of electronic warfare EW 22 Russia reportedly used EW to identify sources of fire artillery mortar and rocket positions and command posts as well as to shut down Ukrainian voice and data communications In one instance in northern Ukraine “every single tactical radio the Ukrainian forces possessed was reportedly taken out by heavy Russian sector-wide EW ”23 Other reported examples of successful Russian EW use included possibly causing Ukrainian UAVs to crash and interfering with the electrical fuses of Ukrainian artillery shells so when they impacted they did not detonate 24 It was also alleged Russia might have conducted Global Position System GPS jamming against Organization for Security and Cooperation in Europe OSCE UAVs used for monitoring the conflict 25 The ability to jam GPS is of particular concern as the U S military could “lose the ability to navigate and tell time and drop

described as significant ground military capabilities primarily captured from the Syrians and Iraqis 27 Some of these systems include Russian T-55 T-72 and U S M-1 tanks captured from Iraq a variety of MANPADs and ATGMs artillery and Russian ZU-23-2 antiaircraft guns and Grad BM-21 multiple rocket launchers 28 The Islamic State has also captured large amounts of small arms and ammunition and given their financial resources was also able to purchase weapons and ammunition The Islamic State experience suggests non-state groups can acquire a wide variety of capable modern weapons either by capturing them in battle or if financial resources permit purchasing them Russian military support of the Asad regime’s fight against U S -backed Syrian rebels and other anti-government factions has been characterized as taking advantage of Syria as a “proving ground”—much like past Arab-Israeli wars—for battle-testing a variety of weapon systems and operational and tactical techniques 29 In terms of weaponry Russia has reportedly provided Syria with T-90 tanks 30 Russian SA-17 advanced air defense systems deployed in Syria reportedly prevented the U S from flying manned air support missions for rebels in key areas in northern Syria in late 2015 because of the air defense system targeting U S planes with their radars 31 Alleged Syrian government and Islamic State use of chemical weapons in both Syria and Iraq has added another dimension to the conflict 32 suggesting nuclear biological and chemical NBC protection for ground combat systems remains a survivability requirement Russia’s military campaign in Syria reportedly has also helped Moscow “market” its weapon systems 33 The Syrian civil war is seen by some as a showcase for Russian-made arms with the Russian government claiming the conflict has “proved the efficiency and reliability in diverse conditions” of Russian weapons 34 Traditionally the largest buyers of Russian weapons have been India China

Association of the United States Army AUSA conference in October 2016 Chief of Staff of the Army General Mark Milley reportedly provided some thoughts on the future operating environment General Milley believes future wars by 2030-2050 will be radically more lethal and savage Because war is ultimately about political will wars will likely be fought in mega-cities which encompass about 70% of the world’s population Cyber electronic warfare EW and robotics will appear in a big way Intelligence surveillance and reconnaissance ISR sensors will be everywhere because of cell phones and internet and noted “If you can be seen you will be hit ” Formations will have to be small dispersed concealed and constantly-moving with General Milley suggesting “If you stay in one place more than 2 or 3 hours you will be dead ” Mega-city fights will be non-linear and the battlefield will be non-contiguous versus historic plains or desert fights Small units must be linked in real-time to long-range-fires Air superiority will not be guaranteed all of the time The Army will have to bring in integrated air and missile defense IAMD to establish initial air superiority for the Air Force and Navy while destroying enemy surface to air missile SAM sites The Army will need to learn to sink ships to be relevant in Pacific Small units will be surrounded most of the time Sustainment will be limited to combat essentials Friendly ports will be attacked Army will have to fight its way in just to get to the real fight Mission command will be degraded most of time from EW and Cyber 48 General Milley’s vision of the future operating environment along with the possibility of confronting a variety of increasingly capable foreign ground combat systems presents a number of considerations for the Army’s ground combat vehicle modernization efforts Possible Implications for Army Modernization The state of international ground combat vehicle modernization lessons from recent and ongoing conflicts and predictions of what the future operating environment holds in store for combatants suggests a number of possible implications for Army modernization efforts These possible implications are discussed first at the general and then at the system level Could U S Ground Combat Systems Be Surpassed by Foreign Systems in the Near Future While most nations of concern continue to upgrade their Cold War era equipment many countries—all with appreciably smaller defense budgets than the U S—are also developing new ground combat systems In pointing out this disparity one defense analyst suggests “Western tank development has ebbed and flowed whereas Russian armored vehicle research has remained almost constant ”49 Countries such as Russia and China are not only upgrading existing ground combat systems with new and effective survivability and lethality features but are also developing entirely new ground combat systems for domestic use and possible export Given the U S has “no new ground combat vehicles under development” and new systems are a “multi-decade effort” due largely to resource constraints and DOD’s Acquisition process there is a possibility one or more upgraded or newly developed foreign ground combat systems could emerge and surpass its This information summarizing General Milley’s comments was provided to CRS by McAleese and Associates on October 10 2016

this occur—even for a single weapon system—it could have significant implications for both the conduct of U S ground combat operations and Army modernization priorities Are Increasingly Capable Foreign Ground Combat Systems an Option for the U S Army On occasion the Army has acquired foreign-developed ground combat systems for use Lacking a dedicated NBC reconnaissance vehicle the Army acquired 60 Fuchs NBC reconnaissance vehicles from Germany modified and re-designated them as the XM-93 Fox and used the vehicle during Operation Desert Storm in 1991 When the Army decided to develop a middle-weight combat force based on a wheeled infantry fighting vehicle instead of opting for a developmental solution the Army selected the General Dynamics Land Systems–Canada LAV-3 8x8 to equip these new brigade combat teams that eventually became Stryker Brigade Combat Teams SBCTs 50 More routinely however the Army adopts foreign components for use A current example of this practice is the ongoing non-developmental APS effort evaluating a number of domestic and foreign APS for possible installation on U S ground combat vehicles 51 As part of the cancelled GCV program the Army conducted an Analysis of Alternatives AoA 52 The GCV AoA evaluated the Israeli Namer IFV the German Puma IFV and the Swedish CV-90 IFV In April 2013 at the request of the former Chairman and former Ranking Member of the Tactical Air and Land Forces Subcommittee of the House Armed Services Committee the Congressional Budget Office CBO released a report titled “The Army’s Ground Combat Vehicle Program and Alternatives ”53 As part of their analysis CBO examined four options 1 2 3 4 purchase the Israeli Namer IFV upgrade the U S Bradley IFV purchase the German Puma IFV and cancel the GCV and recondition Bradley IFVs Based on two sets of metrics—first improvements in protection of soldiers and survivability of the vehicle in combat lethality mobility and capacity and second vehicles that could carry an entire nine soldier squad—CBO recommended that Alternative 3 the Puma would be the most capable vehicle and further noted both the Puma and the upgraded Bradley Alternative 2 would be significantly more capable than the GCV CBO’s study noted however if the Army opted to acquire the Puma it would need to buy five Pumas for every four of its currently Bradley IFVs due to the Puma’s six-man seating capability CBO also suggested the Army’s stated urgency to acquire the GCV was “undercut by the reality that the Army would be unable to widely field it GCV until 2032 ”54 In the study CBO estimated

and the subsequent CBO analysis can be viewed as more than academic The rise of increasingly capable foreign ground combat systems the length of time it takes to develop and field a major combat system under current DOD acquisition regulations and ongoing and anticipated defense budgetary constraints might present policymakers with an opportunity to re-visit the viability of acquiring existing state-of-the art foreign ground combat systems and modifying them to meet Army requirements as has been done in the past Old Threats Are New Again The demise of the Soviet Union led the United States to pursue a “peace dividend ” whereby defense budgets and manpower were drastically reduced in order to decrease taxes and divert budgetary resources to other uses In the end a 535 000 soldier Active Duty force—a more than 30% cut—was agreed at that time constituting the smallest Army since 1939 As part of this reduction based on an assessment of the perceived threat the Army decreased the number of certain types of units and placed less emphasis on particular capabilities Some examples and potential considerations are discussed in the following sections The Air Threat and Short Range Air Defense In its 2016 report to the President and Congress the congressionally mandated 2015 National Commission on the Future of the Army NCFA 55 noted Short-range air defense represents another example of an important shortfall In the postCold War era the Army envisioned little threat from the air forces of potential adversaries Recent activities in Ukraine and Syria have demonstrated the threat environment has changed Yet no short-range air defense battalions reside in the Regular Army Moreover a sizeable percentage of the Army National Guard’s short-range air defense capability is providing essential protection in the National Capital Region leaving precious little capability for other global contingencies including in high-threat areas in northeast Asia southwest Asia Eastern Europe or the Baltics 56 The lack of short-range air defense seemingly represents a significant vulnerability to U S ground forces and ground combat systems to both enemy manned and unmanned aerial systems While the Army might choose to create additional short-range air defense units to protect ground combat units enhanced protection from threat manned and unmanned aerial systems might also need to be incorporated into ground combat systems modernization programs Artillery During the Cold War a robust U S Army artillery capability was seen as a means of countering numerically superior armored and mechanized forces of the Soviet Union and Warsaw Pact Today it is viewed as an important deterrent against North Korean aggression on the Korean Peninsula In a similar manner to short-range air defense field artillery units were cut after the Cold War in part due to the emergence of precision artillery munitions and artillery rounds that dispensed a variety of anti-personnel and anti-vehicle submunitions as well as a belief that U S 55 CRS Report R44366 National Commission on the Future of the Army NCFA Background and Issues for Congress by Andrew Feickert 56 National

Counterparts of U S Army Ground Combat Systems airpower could in many cases be substituted for artillery In its report the National Commission on the Future of the Army recommends among other things an Army and Department of Defense assessment of field artillery capabilities by examining Field artillery capabilities and the changes in doctrine and war plans resulting from U S participation in the Cluster Munitions ban as well as required modernization or munition inventory shortfalls 57 The NCFA in its examination of the Army believed U S participation in the Cluster Munitions Ban has had a detrimental impact on Army field artillery capabilities Results from the examination could include increasing field artillery force structure the development or acquisition of more capable field artillery systems improved artillery munitions or a combination of these courses of action From a threat perspective the proliferation of special munitions—such as precision thermobaric and top attack munitions increasing artillery system capabilities and new tactical techniques have renewed concerns about the potential impact of enemy cannon and rocket artillery on U S combat operations and U S ground combat systems One senior U S Army official contends for example “Russia possesses a variety of rocket missile and cannon artillery systems that outrange and are more lethal than U S Army artillery systems and munitions ”58 Operationally one study noted Russian artillery particularly rocket launchers with conventional thermobaric and cluster munitions—using unmanned aerial systems UAS both for target location and battle damage assessment—is particularly effective against Ukrainian light armor and infantry formations 59 In a similar manner China is reportedly upgrading both its cannon and rocket artillery One study noted The entrance of the Chinese and their greater emphasis om much heavier longer-range rockets that begin to bridge the gap between rocket artillery and short-range ballistic missiles could have a significant effect over time in extending the trend toward longerrange strike systems 60 The dichotomy of diminished U S artillery capability—based on fewer units pending limitations on cluster munitions and shorter effective ranges—versus potential protagonists who possess longer range systems a wider variety of munitions and who are employing innovative target acquisition techniques presents potentially significant battlefield challenges for the U S Army and carries with it implications for modernization as well In terms of modernization enhanced fire control systems permitting a greater rate of fire systems capable of greater ranges and new munitions such as the Guided Multiple Launch Rocket System Alternative Warhead which is designed to be Cluster Munitions Ban-compliant could help to address current shortfalls 57 Ibid p 55 Bryan Bender “The Secret U S Army Study that Targets Moscow ” Politico April 14 2016 59 David Johnson “The

counter-countermeasures and lethal and non-lethal countermeasures The Soviets integrated EW into their routine operations such as security command and control reconnaissance air defense camouflage and deception programs to such an extent that EW became a common feature of Soviet operations in contrast the U S viewed EW more often as an operational afterthought Both the Russian and Chinese armies have dedicated EW brigades and battalions The Vice Chairman of the Joint Chiefs of Staff GEN Paul Selva has suggested “at the tactical level the small-unit level the Russians and the Chinese have a distinct advantage because they have deployed very capable electronic warfare tools ”62 The Association of the United States Army AUSA notes Russian electronic warfare coupled with U S dependence on technology and digital systems create a huge vulnerability for U S forces on the modern battlefield Russia uses electronic warfare for four primary roles 1 Denying communications There are regions in Donbass where no electromagnetic communications—including radio cellphone and television—work 2 Defeating unmanned aerial systems Electronic warfare is the single largest killer of Ukrainian systems by jamming either the controller or GPS signals 3 Defeating artillery and mortars Russian electronic warfare predetonates or duds incoming artillery and mortar rounds that have electronic fusing 4 Targeting command and control nodes Russian electronic warfare can detect all electromagnetic emissions including those from radios Blue Force Tracker Wi-Fi and cellphones which can then be pinpointed with unmanned aerial systems and targeted with massed artillery 63 EW has been viewed as an attractive option for Russia in its conflict in Ukraine It is considered by some analysts as highly effective and as a “non-kinetic form of attack it is harder to trace and less likely to be viewed as overt aggression ”64 The re-emergence of EW in addition to operational and tactical considerations carries with it implications for ground combat systems modernization Across all systems concerted efforts to reduce vehicle electromagnetic emissions could go a long way to reducing vehicle vulnerability to mortar artillery and rocket attack thereby addressing GEN Milley’s concern “if you can be seen detected you can be killed ” Another modernization consideration could be to insure redundant systems are included in vehicle design requirements to compensate where possible for loss of communications GPS access and various FCS functions resulting from a successful EW attack In addition munitions employed by ground combat systems having electronic fuzzes could be “hardened” against EW attacks to preclude pre-detonation or “duds ” 61 Army Field Manual FM 3-36 Electronic Warfare in Operations February 2009 defines Electronic Warfare EW as military action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy Electronic warfare consists of three divisions electronic attack electronic protection and electronic warfare support 62 Sydney J Freedberg Jr “Army Electronic Warfare Investment Lags Russian

adversaries Improvements to vehicle sensors will be necessary to regain the battlefield advantage that the Army enjoyed in 1991 and 2003 due to its early adoption of first and second-generation FLIR systems The Army should invest research and development funds and expand on existing technology to preserve and extend the current tactical advantage these vehicles have in direct fire capability in all weather and visibility Improvements in sensors and direct fire targeting have the potential to substantially affect multiple classes of combat vehicles including the Army’s MBTs the Bradley and its eventual replacement and other systems employing stabilized direct fire weapons such as the Stryker mobile gun system MGS Research and development options that the Army could consider include 1 how to degrade the increasingly capable FLIRs that are appearing on foreign systems and 2 if there other direct fire sensor technologies that could supplement or replace FLIRs in order to maintain the Army’s direct fire advantage 65 Reportedly the Army’s M-1A2 SEP v4 Abrams which is slated to begin testing in 2021 will feature a third generation FLIR which is designed to “allow for better target identification at long ranges and better resolution at short ranges ”66 This improved FLIR is intended to also help crews “better recognize light and heat signatures emerging from targets such as enemy sensors electronic signals or enemy vehicles ”67 While the U S has plans to upgrade its FLIR and FCS other nations are doing so as well One report notes Russian ground forces are slated to upgrade “a number of T-72 and T-90 MBTs with a new automatic target tracker and fire control computer also found on the third-generation T-14 MBT ”68 The T-14’s Kalina target tracker and fire control computer are supposedly “capable of automatically tracking and continuously locking the MBT’s main gun on target based on input from various sensors until the gunner decides to engage the target ”69 As other nations seemingly “close the gap” in terms of FLIR and FCS capabilities Army ground combat system modernization efforts might not only examine other emerging sensor technologies for incorporation into future FCS design but also the means to degrade the FLIRs and FCSs of potential opponent’s ground combat systems 65 John Gordon IV et al Comparing U S Army Systems with Foreign

vehicles and the Dutch plan to mount the Israeli Iron Fist APS on their CV90 IFVs 70 As previously noted the Army is currently involved in two separate parallel and distinct APS efforts—the Expedited Non-Developmental Item NDI APS effort and the Modular Active Protection System MAPS effort The Army’s Expedited NDI APS Program is focused on fielding an existing “hard kill” APS capability in the near term for the Army’s M-1 Abrams tanks M-2 3 Bradley fighting vehicles and the M-1126 Stryker combat vehicle In parallel with the Expedited NDI APS effort the Army is involved with the Modular Active Protection System MAPS effort MAPS is—in and of itself—not an APS but instead a modular framework and controller intended to enable the integration of commercial or government-provided APS subsystems sensors and hard and soft kill countermeasures for current and future combat vehicles While APS is part of the Army’s ground combat system modernization plan it remains to be seen if the Army will aggressively pursue an APS capability for its ground combat vehicles in the near or mid-term or defer until a less risky to dismounted ground troops and civilians and more effective version can possibly be developed in the future Larger Main Armament As the Illustrative Comparison of Selected U S and Foreign Ground Combat Systems tables pages 4-7 depicts and RAND’s “Comparing U S Army Systems with Foreign Counterparts Identifying Possible Capability Gaps and Insights from Other Armies” study suggests there is a trend for larger main armament in MBTs and in particular for tracked IFVs For MBTs in addition to larger caliber main guns some countries are also incorporating autoloaders which can increase the rate of fire for MBTs and offer the possibility of a smaller crew and an unmanned turret One report suggests the Army plans to test the feasibility of having the M-1 Abrams loader crewman controlling supporting unmanned aerial and ground vehicles instead of loading the Abrams main gun thereby requiring the installation of an autoloader on the Abrams 71 For tracked IFVs the trend is towards 30 and 40 mm main armament which provides an enhanced capability to engage both armored vehicles and buildings—the latter being an important consideration given the ever-increasing global trend towards urbanization 72 The Army’s last effort to develop a tracked IFV replacement—the GCV—planned to incorporate a 30 mm cannon into the vehicle’s design so it is possible the Army might continue to pursue a 30 mm cannon in future tracked IFV modernization efforts As previously noted while there are advantages to larger main armament it is also generally considered important that any ground combat vehicles modernization efforts also include concerted efforts to improve existing munitions and develop new munitions based on lessons learned from current conflicts as well as potential future threats An example of such a new munition is the XM1147 Advanced

the U S Army’s sole self-propelled howitzer and it equips all of the Army’s armored brigade combat teams Compared with the field as a whole the M109A6 Paladin is a solid performer in a few key respects but lacks the more powerful gun and automation of the current generation of modern howitzer systems which results in it lacking in range and burst rate of fire relative to many foreign systems The M109A6 Paladin Paladin Integrated Management PIM version entered service in 1992 and is based on the M109 chassis which was originally fielded in 1963 The Army has unsuccessfully attempted to replace Paladin twice in the past decade most recently with the Crusader advanced self-propelled howitzer and the Non-Line-of-Sight Cannon NLOS-C Future Combat Systems vehicle The age and relatively low mobility of Paladin are seen as its most significant weaknesses and as such current Army plans call for a major upgrade entitled PIM PIM mainly consists of a new chassis for Paladin built by BAE Systems and featuring substantial commonality with the Bradley family of vehicles This should help mitigate sustainment and mobility issues but will not address limitations in Paladin’s range and rate of fire In both Operation Desert Storm in 1991 and Operation Iraqi Freedom in 2003 Paladin-equipped artillery units had some difficulty keeping pace with armored units armed with Abrams and Bradley tanks and IFVs Another feature of modern artillery systems is a high degree of automation Paladin has a digitized fire control system and a hydraulic rammer but some systems such as PzH 2000 have much higher levels of automation This permits a high burst rate of fire—up to ten rounds a minute with some systems Due to heating of the barrel the sustained rate of fire on all modern howitzers falls to approximately two rounds per minute over time but for brief periods automated systems provide a significant advantage This extends to the ability to conduct Multiple Round Simultaneous Impact MRSI missions where an individual howitzer with automated loading and laying mechanisms is capable of firing multiple rounds with trajectories and timing that enable the rounds to reach the same target at the same time PzH 2000 has demonstrated the ability to fire a five-round MRSI against a target 17 km away 76 Information in this section is taken from Kris Osborn “The Army’s

restrictions imposed by the U S policy decision to abide by the 2008 Cluster Munitions Ban effectively limits the types of artillery ammunition available for U S military use Modernization solutions addressing this policy could include developing new more capable artillery systems and different types of Cluster Munitions Ban-compliant munitions Examples of new rounds under development include the 5 Inch Multi Service-Standard Guided Projectile SGP which reportedly can deliver accurate fires out to 52 nautical miles as well as a SGP variant which incorporates a sabot with in-flight retargeting

powered projectile with a range of almost 200 kms 78 Developing new munitions could be a financially significant and lengthy undertaking as sufficient stockpiles will need to be built to meet Combatant Commanders’ warfighting requirements as well as for training use Another modernization consideration could be DOD’s and the Army’s NCFA-recommended examination of artillery force structure

well as needed support vehicles and equipment Multiple Launch Rocket Systems MLRS RAND’s research report suggests two system-related trends 1 U S artillery rocket ranges have improved significantly over time but without a continued emphasis on further increases in range GMLRS will begin to be eclipsed by the latest Russian and especially Chinese rocket systems 2 The entrance of the Chinese and their greater emphasis on much heavier longer-range rockets that begin to bridge the gap between rocket artillery and short-range ballistic missiles could have a significant effect over time in

the MLRS family of rockets in its present form In foreign use these heavy rockets are typically under the control of corps or higher-level headquarters the emphasis has remained on conventional missions and the ability to contribute usefully in an environment with limited rules of engagement is a lower priority for the Russian and Chinese militaries When compared with their foreign counterparts the Army’s rocket launchers have a limited suite of warhead options Currently DPICM and HE warheads are the only munitions that MLRS and HIMARS can fire The 2019 submunitions limitations
