Tactical Air Command was established to provide a balance between strategic, air defense, and tactical forces of the post–World War II Air Force. In 1948 the Continental Air Command assumed control over air defense, tactical air, and air reserve forces. After two years in a subordinate role, Tactical Air Command (TAC) was reestablished as a major command. In 1992, after assessing the mission of TAC and to accommodate the decision made regarding Strategic Air Command, HQ United States Air Force inactivated TAC and incorporated its resources into the newly created Air Combat Command.
