It was among the first groups of the Special Forces to be officially formed. The group is responsible for operations in the Pacific. Currently, the First Battalion is stationed at Okinawa while the 2nd, 3rd, and 4th Battalions are stationed at Joint Base Lewis-McChord, Washington with a 4th Battalion standing up in the summer of 2009. 1st Special Forces Group holds the distinction of having the first, Captain Harry Cramer killed 21 October 1957, and last, SGT Fred Mick killed 12 October 1972, Special Forces men killed in Vietnam, as well as the first man, SFC Nathan Chapman killed 4 January 2002, in Afghanistan. Captain Cramer's name was left off the Vietnam Memorial when it was opened in 1982 due to the secretive nature of his mission and that the extent of America's involvement in Southeast Asia was not known in 1957. However, his son appealed to the National Park Service, and in 1983 Captain Cramer's name was added to the Memorial.
