1982 Grunt: Infantry Trooper v1 (straight-arm)
Kirk Bozigian (G.I. Joe Product Manager) isn't afraid to pick favorites, Grunt is the man.
All sixteen 1982 straight-arm figures were re-released in 1983 with updated swivel-arm articulation. The 1982 straight-arm figures are known as v1, while the 1983 swivel-arm figures are known as v1.5, since they aren't entirely new figures.
