What popular 60s action figure featured members of the US armed forces?

G.I. Joe is an American media franchise and a line of action figures owned and produced by the toy company Hasbro. The initial product offering represented four of the branches of the U.S. armed forces with the Action Soldier (U.S. Army), Action Sailor (U.S. Navy), Action Pilot (U.S. Air Force), Action Marine (U.S. Marine Corps), and later on, the Action Nurse. The name is derived from the usage of "G.I. Joe" for the generic U.S. soldier, itself derived from the more general term "G.I.". The development of G.I. Joe led to the coining of the term "action figure". G.I. Joe's appeal to children has made it an American icon among toys.
