Delta Force

The 1st Special Forces Operational Detachment–Delta (1st SFOD-D), referred to variously as Delta Force, Combat Applications Group (CAG), Army Compartmented Elements (ACE), "The Unit", or within Joint Special Operations Command (JSOC), Task Force Green, is a special operations force of the United States Army, under operational control of JSOC. The unit's missions primarily involve counter-terrorism, hostage rescue, direct action, and special reconnaissance, often against high-value targets. Delta Force and its Navy and Air Force counterparts, DEVGRU and the 24th Special Tactics Squadron, are among the U.S. military's "tier one" special mission units tasked with performing the most complex, covert, and dangerous missions directed by the National Command Authority.Delta Force operators are selected primarily from the United States Army Special Operations Command's elite 75th Ranger Regiment and Special Forces, though members can be selected from other special operations units and conventional forces across the Army and sometimes other military branches.
