Delta Force

The 1st Special Forces Operational Detachment–Delta (1st SFOD-D), also known as Delta Force, Combat Applications Group (CAG), or within Joint Special Operations Command (JSOC) as Task Force Green, is a special operations force of the United States Army under the 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 the Intelligence Support Activity, and 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 and combat support members are selected from the Army Special Operations Command's 75th Ranger Regiment and U.S. Army Special Forces, though selection is open to other special operations and conventional units across the Army and other military branches.
