a special logbook. Vehicles During the Green Berets' missions in other nations, they would use Ground Mobility Vehicle (GMV)-S Humvees for various uses or purpose built technicals for patrol on rugged terrain which would help preserve the clandestine nature of their missions. They have also had access to the M1288 GMV 1.1 variant of the Army Ground Mobility Vehicle made by General Dynamics as well as the Oshkosh M-ATV Special Forces variant MRAPs. For aircraft other than the ones used by the US military and its special forces/special operations forces units, they extensively used the CIA-operated Mi-8 and Mi-17 variants of those military helicopters in Afghanistan during the initial stages of Operation Enduring Freedom.

The Army Special Forces were established in 1952, ten years before the Navy SEALs, and 25 years before Delta Force. Every other modern U.S. special operations unit in the Army, Navy, Air Force, and Marines was established after 1977. In Veritas: Journal of Army Special Operations History, Charles H. Briscoe states that the Army "Special Forces did not misappropriate the appellation. Unbeknownst to most members of the Army Special Operations Force (ARSOF) community, that moniker was adopted by the Special Forces in the mid-1950s." He goes on to state that all qualified enlisted and officers in Special Forces had to "voluntarily subscribe to the provisions of the 'Code of the Special Forces Operator' and pledge themselves to
