Exercise Campaign Reforger ("REturn of FORces to GERmany") was an annual military exercise and campaign conducted by NATO 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. Although most troops deployed were from the United States, the operation also involved a substantial number of troops from other NATO countries including Canada and the United Kingdom. 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 Once the Cold War ended, it was superseded by other exercises.

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.^[1] 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.

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.^[2]

Exercise Reforger 1988 is held to be the largest exercise during the Cold War.^[3] Involving around 125,000 troops, it was billed as the largest European ground maneuver since World War II.^[4]

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.^[4]

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 after due to German reunification, the dissolution of the Soviet Union and the Warsaw Pact, and the end of the Cold War.
