South Carolina. On 21 September 1956, the Army established the 101st again as a training unit by transferring its colors, then at a training command at Fort Jackson, SC, to Fort Campbell, KY. The departure of the 11th Airborne Division for NATO duty in West Germany meant that the Army needed another rapidly deployable unit to face Cold War contingencies. The reactivated 101st was formed using the assets of the 187th and 508th Airborne RCTs, plus volunteers from the inactivating 6th Infantry Division run through parachute school either at Fort Campbell or Fort Benning. The division of 1956 was much different from the wartime pattern. There were tight military budgets for conventional forces in the Nuclear Age since the predominant belief was that battlefield nuclear weapons would be used early and often. This in turn made riflemen obsolete. This, combined with the fact the new 101st would be built from scratch, made the division a test of what was called a Pentomic, for "pentagonal atomic" division. The division was made up of five "battle groups", each one consisting of five companies (1 headquarters company, four rifle companies) plus a heavy mortar section. There was even a nuclear-armed rocket battery in Division Artillery. But there was only room for one "battle group" of each of the 101st's old regiments (327th, 501st, 502nd, and 506th, with the 187th coming in from the 11th). The lineage of the 502d was revived with the activation on 25 April 1957 of HHC, 1st Airborne Battle Group, 502d Infantry (bearing a lineage going back to Company A of the original 502nd PIB) as a unit within the 101st. As the rest of the Army converted to the Pentomic structure, the 2d Airborne Battle Group, 502nd Infantry was activated on 1 March 1957 in West Germany by reflagging existing elements of the 11th Airborne Division. Perpetuating the lineage of Company B, 502d PIB and thus the World War II 2d Battalion, it was inactivated on 1 July 1958 when the 11th itself was inactivated. Its personnel and equipment were reflagged to other unit designations under the 24th Infantry Division, which retained a partial Airborne capability with two battle groups (1-187th and 1-503d) before they rotated back to the United States to become part of the 82d Airborne Division. Their departure from the 24th was concurrent with the arrival of two non-airborne battle groups arriving from the United
