G.I. Joe is a line of action figures offering representations of four of the branches of the U.S. armed forces with the Soldier (Army), Action Sailor (Navy), Action Pilot (Air Force) and Action Marine (Marines). When remarking that she played with dolls, Samantha Carter was aksed if it was G.I. Joe, but she said it was in fact Major Matt Mason. (SG1: "Children of the Gods")
