Organisations: JSOC ------------------------ The Joint Special Operations Command (JSOC)is the 'joint headquarters designed to study special operations requirements and techniques; ensure interoperability and equipment standardization; plan and conduct joint special operations exercises and training; develop joint special operations tactics.' For this task, the Joint Communications Unit is tasked to ensure compatibility of communications systems and standard operating procedures of the different special operations units. The Joint Special Operations Command also oversees the Special Mission Units of U.S. Special Operations Command. These are elite special operations forces units that perform highly classified activities. The Intelligence Support Activity's primary role is as a deep reconnaissance, intelligence-gathering special mission unit, in support of DEVGRU and Delta Force. Delta Force and DEVGRU are the military's primary counter-terrorism units, eliminating high-value targets and performing hostage rescues are their main roles, along with special reconnaissance and direct action assignments. The 24th Special Tactics Squadron attaches personnel as enablers to these two units such as Combat Controllers to provide air traffic control and fire support, Pararescuemen to provide combat medicine and combat search and rescue, and Tactical Air Control Party specialists to co-ordinate close air support. The Joint Communications Unit provides communications capabilities. Units from the Army's 75th Ranger Regiment and 160th Special Operations Aviation Regiment are controlled by JSOC when deployed as part of JSOC Task Forces such as Task Force 121 and Task Force 145. JSOC has an operational relationship with the CIA's Special Activities Center (SAC). SAC's Special Operations Group (SOG) often recruits from JSOC SMU personnel. DEVGRU ------------------------ The typical SEAL platoon has an OIC (Officer in Charge, usually an O-3), an AOIC (Assistant Officer in Charge, usually an O-2), a platoon chief (E-7), an LPO (Leading Petty Officer, E-6) and others ranging from E-6 to E-4 (most are E-5). Occasionally there is a 'third O'. Usually the third O is an O-1 on his first operational deployment. This makes the platoon consist of 3 officers and 13 enlisted personnel. The core leadership in the Troop and Platoon are the Commander/OIC and the Senior Enlisted NCO (Senior Chief/Chief). Troop core skills consist of: Sniper, Breacher, Communicator, Maritime/Engineering, Close Air Support, Corpsman, Point-man/Navigator, Primary Driver/Navigator (Rural/Urban/Protective Security), Heavy Weapons Operator, Sensitive Site Exploitation, Air Operations Master, Lead Climber, Lead Diver/Navigator, Interrogator, Explosive Ordnance Disposal, Technical Surveillance, and Advanced Special Operations. In 1987, SEAL Team 6 was renamed to the United States Naval Special Warfare Development Group, although members are still frequently referred to informally as 'SEAL Team 6'. SFOD-D ------------------------ 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 counterterrorism, hostage rescue, direct action, and special reconnaissance, often against high-value targets. Delta Force are the U.S. military's tier one special mission unit 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. Each troop has four teams, each one led by a team leader, a Master Sergeant (E-8) or Sergeant First Class (E-7), and an assistant team leader who can also have the same rank. Each team can have as many as twelve, or as few as one or two operators. 160th SOAR(A) ------------------------ The 160th Special Operations Aviation Regiment (Airborne), abbreviated as 160th SOAR(A), is a special operations force of the United States Army that provides helicopter aviation support for special operations forces. Its missions have included attack, assault, and reconnaissance, and these missions are usually conducted at night, at high speeds, low altitudes, and on short notice. Nicknamed the Night Stalkers and called Task Force Brown within the JSOC, the 160th SOAR has headquarters at Fort Campbell, Kentucky. US Armed Forces Special Operations Warfare Doctrine 2012.
