In May 1986, the Goldwater-Nichols Department of Defense Reorganization Act led to the formation of the United States Special Operations Command. Senators William Cohen and Sam Nunn introduced the Senate bill, and the following month Congressman Dan Daniel introduced a like measure in the House of Representatives. The key provisions of the legislation formed the basis to amend the 1986 Defense Authorizations Bill. This bill, signed into law in October 1986, in part directed the formation of a unified command responsible for special operations. In April 1987, the DoD established the United States Special Operations Command (USSOCOM) at MacDill Air Force Base, Florida, and Army GEN James J. Lindsay assumed command. Four months later, 23 AF moved its headquarters from Scott AFB to Hurlburt Field, Florida.
