The 8th Special Forces Group of the United States Army was established in 1963 at Fort Gulick, Panama Canal Zone. The primary mission of the 8th Special Forces Group (Airborne) [(SFG(A)] was counter-insurgency training for the armies of Latin America. Some training was performed under the sponsorship of the School of the Americas, also located at Fort Gulick
In May 1962, the advance party from Company D, 7th SFG(A) departed from Ft. Bragg, NC to Fort Gulick, Panama, at that time in the Panama Canal Zone, to establish the 8th SFG(A). Three months later, in August 1962, Major Melvin J. Sowards, Commander of Company D, 7th SFG(A) moved the main body of the company to the Canal Zone. They would be followed by augmentation detachments. Upon their arrival, the basic organization of the Special Action Force (SAF) was completed and Lieutenant Colonel Sawyer assumed command. The legendary Lieutenant Colonel Arthur D. Simons, aka "Bull", then took command of Company D, 7th SFG(A) 18 January 1963 and LTC Sawyer became the Executive Officer. On 12 April 1963, under the command of LTC Simons, the SAF elements of the 7th SFG(A) were officially redesignated, as authorized by the Department of the Army and the 8th SFG(A) was activated.
The United States Army Special Forces, colloquially known as the Green Berets due to their distinctive service headgear, are a special operations force tasked with five primary missions: unconventional warfare (the original and most important mission of Special Forces), foreign internal defense, special reconnaissance, direct action, and counter-terrorism. The first two emphasize language, cultural, and training skills in working with foreign troops. Other duties include combat search and rescue (CSAR), counter-narcotics, counter-proliferation, hostage rescue, humanitarian assistance, humanitarian demining, information operations, peacekeeping, psychological operations, security assistance, and manhunts; other components of the United States Special Operations Command (USSOCOM) or other U.S. government activities may also specialize in these secondary areas. Many of their operational techniques are classified, but some nonfiction works and doctrinal manuals are available.[7][8][9]
As special operations units, Special Forces are not necessarily under the command authority of the ground commanders in those countries. Instead, while in theater, SF units may report directly to a geographic combatant command, USSOCOM, or other command authorities. The Central Intelligence Agency's (CIA) highly secretive Special Activities Division (SAD) and more specifically its Special Operations Group (SOG) recruits from the Army's Special Forces. Joint CIA–Army Special Forces operations go back to the MACV-SOG branch during the Vietnam War. The cooperation still exists today and is seen in the War in Afghanistan
