Currently, after major redesignations and reorganizations, AFSOC direct reporting units include the 16th Special Operations Wing, the 352nd Special Operations Group, the 353rd Special Operations Group, the 720th Special Tactics Group (720 STG), the USAF Special Operations School and the 18th Flight Test Squadron (18 FLTS). During the early 1990s a major reorganization occurred within AFSOC. The 1720 STG became the 720 STG in March 1992; the transfer of ownership of Hurlburt Field from Air Mobility Command (AMC, and formerly MAC) to AFSOC in October 1992, followed by the merger of the 834th Air Base Wing (834 ABW) into the 1 SOW, which assumed host unit responsibilities. A year later the 1 SOW became the 16 SOW in a move to preserve Air Force heritage.
