Headquarters EUCOM initially shared the I.G. Farben Building in Frankfurt, Germany, with Headquarters United States Army, Europe. By 1953 over 400,000 U.S. troops were stationed in Europe. In 1954, the headquarters moved to Camp des Loges, a French Army base west of Paris and a short distance from SHAPE. There, EUCOM prepared plans for the defense of Western Europe within the NATO framework against the Soviet Union and Warsaw Pact. EUCOM used the Military Assistance Program to help its NATO partners build their military capabilities, including after 1955 the German Bundeswehr. In 1955, EUCOM established a Support Operations Command Europe, soon renamed Support Operations Task Force Europe (later Special Operations Command Europe) for special operations missions. In 1961, EUCOM began operating an airborne command post, Operation Silk Purse.
