Cold War history from the 1950s of U.S. armor headquartered at Frankfurt (and therefore having an orientation that included the Fulda Gap): shows 4th Armor Group attached to V Corps, along with the U.S. divisions, 2d Armored Div, 3d Armored Div, and 10th Infantry Div. USAREUR Troop Lists dated 30 June 1958 show V Corps as containing 3rd Armored Div.(HQ Frankfurt), 8th Infantry Div. (HQ Bad Kreuznach), 4th Armor Group (HQ Frankfurt), and 3rd Infantry Div. (which was headquartered at Würzburg). After the 1963 ROAD reorganization, the 4th Armor Group was inactivated, and the 3rd Infantry Division headquartered at Würzburg was reassigned to VII Corps. The deployment of the 3rd Armored Division and the 8th Infantry Division to V Corps remained stable until the end of the Cold War. In practice, it was unknown how effective V Corps would have been in the event of war due to the vast numbers of tanks and infantry that the Soviets were able to field. In response to the quantitative superiority of the Soviet forces, the U.S. deployed Atomic Demolition Mines for many years in the Fulda Gap. In the early '60s, the Fulda Gap was also protected by V Corps Artillery units equipped with the medium-range MGM-5 Corporal guided missile capable of carrying nuclear warheads. In 1962, the more reliable solid fuel MGM-29 Sergeant missile was deployed and remained in use until 1973 when it was replaced by the MGM-52 Lance missile.
