1st Special Forces Operational Detachment-Delta

The 1st Special Forces Operational Detachment–Delta (1st SFOD-D), referred to variously as Delta Force, Combat Applications Group (CAG), Army Compartmented Elements (ACE), 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 counterterrorism, hostage rescue, direct action, and special reconnaissance, often against high-value targets. Delta Force, along with its Navy and Air Force counterparts, DEVGRU (SEAL Team Six) and the 24th Special Tactics Squadron, are the U.S. military's tier one special mission units that are tasked with performing the most complex, covert, and dangerous missions directed by the President of the United States and the Secretary of Defense. Most Delta Force operators are selected from the Army Special Operations Command's elite 75th Ranger Regiment and U.S. Army Special Forces, though selection is open to other special operations units and conventional forces across the Army and sometimes other military branches.
