Exercise Campaign Reforger ("return of forces to Germany") was an annual military exercise and campaign conducted by NATO from 1969 until 1993 during the Cold War. The exercise was intended to ensure that NATO had the ability to quickly deploy forces to West Germany in the event of a conflict with the Warsaw Pact. It was a basic military planning exercise to smooth out issues in the event of an invasion of western Europe, not just a show of force. Once the Cold War ended, it was superseded by other exercises. Although most troops deployed were from the United States, the operation also involved a substantial number of troops from other NATO countries including Belgium, Canada, France, Netherlands, and the United Kingdom.[1][2]
The last Reforger exercise was Reforger 93. Exercise Steadfast Defender is the most similar military exercise that has taken place in the 21st century, also involving North American troops deploying across the Atlantic Ocean to exercise with European NATO allies.[3] There is also the biennial Exercise Bright Star that involves operations in the Middle East. However, while NATO members (and other countries friendly to Egypt and the US) are free to participate, Exercise Bright Star is not a NATO exercise.
History
[edit]The Reforger exercise itself was first conceived in 1967. During the ongoing Vietnam War, U.S. President Lyndon Johnson announced plans to withdraw approximately two divisions from Europe in 1968. As a demonstration of its continuing commitment to the defense of NATO and to illustrate its capability of rapid reinforcement, a large scale force deployment was planned that would deploy a division or more to West Germany in a regular annual exercise. The first such exercise was conducted beginning on 6 January 1969.[4]

Exercise Reforger 1988 is held to be the largest exercise during the Cold War.[5] Involving around 125,000 troops, it was billed as the largest European ground maneuver since World War II.[6]
These exercises continued annually past the end of the Cold War, except for the year 1989, until 1993. Reforger 75 marked the operational presence of the U.S. Marine Corps in Europe for the first time since World War I, when the 2nd Marine Division's 32nd Marine Amphibious Unit was deployed from Camp Lejeune, North Carolina as part of that exercise.[6]
Reforger was not merely a show of force—in the event of a conflict, it would be the actual plan to strengthen the NATO presence in Europe.[citation needed] In that instance, it would have been referred to as Operation Reforger. Important components in Reforger included the Military Airlift Command, the Military Sealift Command, and the Civil Reserve Air Fleet.

The U.S. Army also increased its rapid-reinforcement capability by prepositioning huge stocks of equipment and supplies in Europe at POMCUS sites. The maintenance of this equipment has provided extensive on-the-job training to reserve-component support units.
The last Reforger exercise was Reforger 93. No further Reforger exercises were held due to German reunification, the dissolution of the Soviet Union and the Warsaw Pact, and the end of the Cold War.

Cold War Context and Inception
During the Cold War, NATO faced the persistent threat of a potential Soviet-led Warsaw Pact invasion of Western Europe, where the alliance maintained a strategy of forward defense reliant on both stationed forces and rapid reinforcements from the United States. By the mid-1960s, the Soviet Union had amassed over 500,000 troops and thousands of tanks in Eastern Europe, underscoring the need for credible deterrence through demonstrable reinforcement capabilities.[3][1] US troop commitments in Europe, peaking at around 400,000 in the early 1960s, began declining amid the Vietnam War and fiscal pressures, dropping to approximately 300,000 by 1968, which heightened concerns among NATO allies about America's ability to surge forces across the Atlantic in a crisis. This reduction, coupled with the alliance's dependence on prepositioned equipment stocks in Germany, necessitated exercises to validate logistics, deployment timelines, and interoperability against a numerically superior adversary.[3][4] Exercise REFORGER, acronym for Return of Forces to Germany, was inaugurated in January 1969 as REFORGER I to test and affirm NATO's capacity for swift transatlantic reinforcement, involving the deployment of over 12,000 US soldiers who linked up with prepositioned materiel in West Germany. The exercise simulated wartime mobilization, emphasizing sealift and airlift operations to counter Warsaw Pact aggression, and served as an annual signal of resolve to both allies and potential foes.[2][3][4]Core Strategic Goals
The core strategic goals of Exercise Reforger centered on validating the rapid reinforcement of NATO's Central Front in Europe against potential Warsaw Pact invasion, primarily by testing the United States' capacity to deploy tens of thousands of troops and equipment across the Atlantic within days to weeks.[5][4] These exercises operationalized NATO's Forward Defense doctrine and Flexible Response strategy, emphasizing conventional force buildup to counter Soviet numerical superiority without immediate reliance on nuclear escalation, as articulated in U.S. defense planning from the late 1960s onward.[4] For instance, early iterations like REFORGER I in 1969 aimed to redeploy approximately 12,000 troops to Germany, evolving by the 1980s to simulate five U.S. divisions arriving within 30 days, supported by pre-positioned matériel in POMCUS sites.[4] A parallel objective was to enhance logistical and operational readiness through full-scale testing of sealift, airlift, and sustainment systems, including integration with NATO allies' infrastructure.[5] This involved joint exercises across U.S. branches—such as the Air Mobility Command and Military Sealift Command—and occasional inclusion of units like the 36th Marine Amphibious Unit in REFORGER 75, ensuring seamless marriage of deploying personnel with prepositioned equipment upon arrival in West Germany.[5] Such drills addressed vulnerabilities exposed in prior operations, like the 1963 Big Lift, by refining command-and-control processes and terrain familiarization for reinforcing units.[4] Deterrence formed an overarching goal, with REFORGER serving as a visible demonstration of U.S. resolve to Soviet observers, thereby bolstering alliance cohesion and discouraging aggression through proven reinforcement feasibility.[3][5] By annually showcasing interoperability—such as airlifting 19,000 troops in REFORGER 83—the exercises reinforced diplomatic assurances to European allies amid domestic U.S. debates over defense spending, underscoring NATO's collective defense credibility.[3][4]Historical Development
Early Phases (1969–1979)
Exercise REFORGER, short for Return of Forces to Germany, was initiated in 1969 as an annual NATO exercise to test the rapid deployment and reinforcement of allied forces to Western Europe in response to potential Warsaw Pact aggression.[6] The inaugural iteration, REFORGER I, began on January 6, 1969, with U.S. ground troops arriving at Frankfurt Airport aboard C-141 Starlifter aircraft.[7] More than 12,000 U.S. Soldiers participated, focusing on the integration with pre-positioned equipment stocks in Germany to simulate swift assembly of combat-ready units.[2] Deployment proceeded to training areas such as Nuernberg, where coordination occurred despite inclement weather, culminating in redeployment phases by early February.[8][9] The early exercises emphasized logistical validation, including airlift and sealift capabilities, as well as the "marriage" of arriving personnel with prepositioned materiel configured to unit sets (POMCUS).[1] Soviet authorities criticized REFORGER I as a major military provocation, highlighting its deterrent signaling amid Cold War tensions.[6] V Corps units from the U.S. were central, underscoring the commitment to NATO's central front defense.[6] Through the 1970s, REFORGER continued annually, refining procedures and addressing operational challenges, such as funding shortfalls that limited participation of elements like the 3rd Squadron, 3rd Armored Cavalry Regiment in REFORGER II in 1970.[4] These phases prioritized deployment efficiency and interoperability with NATO allies, laying groundwork for larger-scale maneuvers in subsequent decades while demonstrating U.S. resolve to reinforce Europe promptly.[3] Participation scales remained in the tens of thousands, focusing on corps-level reinforcements without the extensive field training assemblies seen later.[2]Escalation in the 1980s
During the 1980s, REFORGER exercises expanded significantly in scope and participation amid heightened East-West tensions, including the Soviet invasion of Afghanistan in 1979 and the Reagan administration's military buildup to counter perceived Soviet aggression.[3] This escalation aligned with increased U.S. defense spending, which rose from $134 billion in fiscal year 1980 to $253 billion by 1985, enabling larger-scale deployments to demonstrate NATO's rapid reinforcement capabilities against a potential Warsaw Pact offensive.[1] The exercises grew from typical involvement of 40,000 to 50,000 troops in earlier years to over 100,000 by the late 1980s, incorporating multiple divisions, advanced equipment, and allied forces for enhanced interoperability testing.[1] In REFORGER 1982, the U.S. Army's III Corps led operations with substantial NATO ally participation, focusing on rapid sealift and airlift of heavy forces to West Germany.[1] REFORGER 1983, part of the Autumn Forge series, involved the airlift of 16,044 U.S. troops alongside ground maneuvers simulating frontline reinforcement.[10] By mid-decade, exercises incorporated newer systems like the M2 Bradley infantry fighting vehicle, as seen in 1984 iterations emphasizing combined arms tactics in European terrain.[3] REFORGER 1987 mobilized 115,000 troops from six NATO militaries, testing logistics across the Atlantic under realistic combat conditions.[11] The pinnacle came with REFORGER 1988, deploying approximately 125,000 personnel—the largest European ground maneuver since World War II—validating prepositioned stocks and surge deployment procedures critical for deterrence.[3] These amplifications underscored NATO's commitment to credible defense, though they occasionally heightened Soviet anxieties, as evidenced by intelligence assessments of potential misinterpretations during overlapping exercises like Able Archer 83.[10]Termination and Immediate Aftermath (1990–1993)
In early 1989, amid Soviet leader Mikhail Gorbachev's peace initiatives and declining East-West tensions, the United States decided to reduce its participation in the annual REFORGER exercise, reflecting a broader reassessment of NATO's reinforcement needs.[12] The 1990 iteration, REFORGER 90, proceeded in January but on a scaled-down basis, involving approximately 75,000 troops overall—fewer than in prior years—and focusing on lighter, more agile deployments without the full scope of heavy mechanized reinforcements typical of earlier exercises.[13] It featured U.S. units including the 1st Infantry Division, 2nd Armored Division, and 10th Mountain Division, alongside NATO allies, to test rapid sealift and airlift capabilities amid the accelerating collapse of communist regimes in Eastern Europe.[14] Subsequent exercises in 1991 and 1992 maintained the annual cadence but continued the trend of reduction, as the Gulf War (1990–1991) diverted resources and attention while underscoring shifts toward expeditionary operations rather than European theater reinforcement.[1] The final exercise, REFORGER 93, occurred in May 1993 with markedly diminished scale, relying predominantly on U.S. forces already in Europe and involving only limited additional deployments, signaling the program's obsolescence in a post-Cold War environment.[3] The termination of REFORGER after 1993 stemmed directly from the Soviet Union's dissolution on December 25, 1991, and the Warsaw Pact's earlier disbandment on July 1, 1991, which eliminated the primary existential threat justifying large-scale transatlantic reinforcements.[15] In the immediate aftermath, NATO closed most prepositioned equipment storage sites in Europe, including key POMCUS facilities in Germany, and withdrew or redistributed stored materiel as alliance priorities pivoted from deterring Warsaw Pact aggression to managing regional instabilities and peacekeeping.[16] This transition facilitated U.S. force reductions in Europe under the Clinton administration's "peace dividend" policies, with troop levels dropping from over 200,000 in 1990 to around 100,000 by 1993, though it later prompted debates over diminished readiness for potential future contingencies.[17]Participating Forces and Structure
United States Contributions
The United States contributed the primary reinforcing forces to Exercise Reforger, deploying approximately 40,000 to 50,000 troops annually from the continental United States to West Germany to simulate rapid reinforcement of NATO's central front.[1] These deployments tested the US military's ability to transport personnel via airlift and integrate them with prepositioned equipment stored at Prepositioned Organizational Materiel Configured to Unit Sets (POMCUS) sites across Europe.[1] US Army units formed the core of these contributions, including mechanized and armored divisions such as elements of the 1st Infantry Division from Fort Riley, Kansas, and the 2nd Armored Division.[1][18] For instance, during REFORGER 87, over 6,000 pieces of equipment from Fort Riley were transported by rail to the port of Beaumont, Texas, for sealift to Europe, demonstrating the scale of logistical support required.[1] Troops upon arrival would "marry up" with pre-stocked vehicles, including M60 tanks, M113 armored personnel carriers, and later M2 Bradley fighting vehicles, enabling full combat readiness within days.[3][18] The US Air Force played a critical supporting role, conducting massive airlifts of personnel; in Autumn Forge 83, which encompassed REFORGER, 16,044 US troops were airlifted to Europe using 84 C-141 Starlifter sorties.[10] This inter-service coordination enhanced rapid deployment timelines, with exercises like REFORGER V in 1973 involving up to 51,000 troops in field training phases.[1] Prepositioned stocks, managed under programs evaluated by the Government Accountability Office, included repair parts and supplies issued at varying stock levels to support sustained operations.[19] These contributions underscored the US commitment to NATO deterrence, with REFORGER exercises from 1969 onward validating the feasibility of reinforcing Europe against potential Warsaw Pact aggression through empirical testing of deployment speeds and unit cohesion.[3][5]NATO Allied Involvement
NATO allied involvement in Exercise Reforger primarily centered on host nation support, joint maneuver training, and integration with U.S. reinforcing forces during the exercise's combat simulation phases, such as those under the broader Autumn Forge series. West Germany, as the primary host, provided critical infrastructure including rail networks, ports, airfields, and vast training areas like the Grafenwöhr and Hohenfels ranges, enabling the reception and staging of up to 100,000 U.S. troops annually by the 1980s. The Bundeswehr contributed thousands of personnel as blue force elements, simulating integrated NATO defenses against a hypothetical Warsaw Pact invasion, while also handling logistical coordination and civil-military liaison to minimize disruptions in populated areas.[1] Other NATO members participated selectively, often deploying armored, infantry, and support units to enhance multinational interoperability. In REFORGER 87's Certain Strike phase, forces from five allied nations—West Germany, the Netherlands, Belgium, the United Kingdom, and Canada—joined 35,000 U.S. combat soldiers, totaling 115,000 personnel across six countries, with approximately 78,000 troops, 20,000 wheeled vehicles, and 2,200 tracked vehicles engaged in maneuvers across northern and central West Germany.[20][21] The United Kingdom contributed elements like Challenger 1 tank squadrons from regiments such as The Queen's Royal Hussars, focusing on armored warfare integration, while Dutch and Belgian units provided mechanized infantry and artillery support.[22] Canada's involvement typically included smaller contingents from its European-based brigade, emphasizing rapid response and NATO command structures.[20] Allied contributions extended beyond ground forces to include air and logistical elements, with nations like the UK and Netherlands providing tactical air support and sealift augmentation via national assets. These roles tested NATO's collective defense doctrine under Article 5, verifying command-and-control linkages and sustainment chains amid real-world constraints such as congested European rail lines. Participation varied by year, peaking in the 1980s amid heightened East-West tensions, but remained secondary to U.S. reinforcements, reflecting allies' reliance on American rapid deployment for credible deterrence.[3][1]Operational Mechanics
Deployment and Logistics
The deployment phase of Exercise Reforger emphasized rapid transatlantic movement of U.S. and NATO forces from North America to West Germany, simulating reinforcement against a Warsaw Pact incursion. Personnel, typically numbering in the tens of thousands per iteration—reaching 125,000 in Reforger 1988—were primarily transported via airlift using the Military Airlift Command, augmented by the Civil Reserve Air Fleet and commercial charter flights.[1] This enabled division-sized elements to cross the Atlantic in approximately 2-3 days, with troops arriving at airfields such as Ramstein or Frankfurt before proceeding to reception centers.[23] Heavy equipment deployment relied heavily on prepositioned materiel configured to unit sets (POMCUS) stored at sites across West Germany, the Netherlands, and Belgium, allowing arriving units to rapidly equip and mobilize without awaiting full sealift.[4][24] For instance, in Reforger 87, units from Fort Riley, Kansas, shipped around 6,000 pieces of equipment via 34 trains comprising 1,900 railcars to the port of Beaumont, Texas, for sealift to European ports like Bremerhaven or Antwerp.[1] From there, cargo moved inland by rail and road to POMCUS facilities or exercise areas, coordinated through the U.S. Military Traffic Management Command and host-nation infrastructure, including Germany's rail network for onward distribution.[25] Logistics encompassed the full spectrum of reception, staging, onward movement, and integration (RSOII), testing sustainment chains from U.S. departure points to forward assembly in the Central Region. The Military Sealift Command handled ocean transport of non-prepositioned assets, while European allies provided critical host-nation support, such as port handling and rail capacity, to validate NATO's reinforcement timelines.[1][26] This structure underscored Reforger's role in rehearsing just-in-time logistics, though critics within U.S. Army Europe noted its dependence on prepositioning as potentially overstating wartime sealift feasibility.[1]Training and Simulation Elements
Exercise Reforger incorporated a mix of live training and simulated elements to prepare U.S. and NATO forces for rapid reinforcement of Europe, emphasizing deployment logistics, unit integration, and command decision-making under wartime conditions. Live components focused on field training exercises (FTX) involving actual troop movements, equipment handling, and tactical maneuvers across West German terrain, allowing units to practice reception, staging, onward movement, and integration (RSOI) with in-place NATO allies.[27] Command field exercises (CFX) extended this by training mid-level elements in field conditions with partial live forces augmented by simulated opposing forces, testing real-time coordination without full-scale combat.[28] Simulations played a growing role, particularly in command post exercises (CPX), where only staff and command elements participated—either in the field or garrison—to rehearse battle planning, fire support, and logistics via computer models, mitigating risks and costs associated with live play. Systems like the Corps Battle Simulation (CBS) enabled corps-level staffs to simulate large-scale engagements, while tools such as SIMNET provided immersive, networked views of battlefield dynamics for crew and small-unit training.[29] In REFORGER 1990, these simulations enhanced command/control training and reduced transportation costs by over $4 million compared to prior iterations, alongside projected 40% lower maneuver damage claims from decreased live vehicle use.[29] By the early 1990s, advanced distributed interactive simulations (DIS) and protocols like Aggregate Level Simulation Protocol (ALSP) were integrated, as in REFORGER 1992, to network virtual and constructive models across units, enabling satellite-linked maneuvers against simulated adversaries at reduced expense—costing less than half of previous fully live exercises.[30] [31] These elements addressed live training limitations, such as traffic congestion and environmental impacts, while improving interoperability and higher-echelon readiness without deploying full forces.[29] Map-based tools like JANUS further supported platoon- and company-level indirect simulations for staff coordination in REFORGER scenarios.[29] ![U.S. Army during REFORGER '82][float-right]CFX and CPX often incorporated opposing forces (OPFOR) simulated via role-players or basic models to replicate Warsaw Pact threats, fostering realistic decision cycles and electronic warfare training.[32] Overall, this hybrid approach validated NATO's reinforcement doctrine, with simulations evolving to handle complex variables like sustainment and intelligence portrayal, though early efforts noted weaknesses in enemy representation.[29]

REFORGER exercises occurred annually from 1969 to 1993, with each iteration testing the rapid deployment of U.S. and NATO forces to West Germany via air and sea lift, followed by integration into defensive maneuvers against simulated Warsaw Pact aggression.[1] These iterations evolved in complexity, incorporating prepositioned equipment sets and multinational participation, though troop deployments from the U.S. typically ranged from 10,000 to over 30,000 personnel per exercise.[29] The inaugural REFORGER I, conducted in January 1969, marked the return of more than 12,000 U.S. Soldiers to Europe, validating the concept of reinforcing NATO's central front from continental bases.[33] Subsequent early iterations in the 1970s, such as REFORGER 74 and REFORGER 76, emphasized armored and mechanized unit movements, including M113 armored personnel carriers and preparations from U.S. installations like Fort Hood, Texas.[34] In the 1980s, exercises peaked in scale and realism; REFORGER 82 featured leadership by the U.S. III Corps in major field training, while REFORGER 83, under the Autumn Forge 83 umbrella, involved a radio-silent airlift of 16,044 U.S. troops across 84 C-141 flights, heightening Soviet perceptions of imminent conflict.[1] [10] The zenith came with REFORGER 88 (Certain Challenge), spanning August to November 1988, which mobilized 125,000 soldiers in the largest such maneuver since World War II, testing rear-area threats and host-nation support amid extensive civilian disruptions.[1] [35] Post-Cold War drawdowns reduced scope; REFORGER 90 employed fewer units than prior decades, REFORGER 91—postponed from 1989 and amid Gulf War demands—limited participation to 28,000 allied troops with simulation-heavy components, and REFORGER 93 concluded the series amid German reunification and Warsaw Pact dissolution.[36] [37]| Year | Key Features | Approximate U.S./Allied Troops Deployed |
|---|---|---|
| 1969 (REFORGER I) | Initial validation of reinforcement concept; focused on air/sea lift to Europe | >12,000 U.S. Soldiers[33] |
| 1983 | Radio-silent airlift as part of Autumn Forge; linked to Soviet war scare | 16,044 U.S. troops airlifted[10] |
| 1988 (Certain Challenge) | Largest iteration; extensive field training and logistics testing | 125,000 total soldiers[1] |
| 1991 | Simulation-reliant due to Gulf War; postponed from 1989 | 28,000 allied troops[36] |
