We've got some great Vietnam Vet archetypes in the movies and TV. I feel that we have far far more good ones in real life, but, it is helpful to know the touchstones of the past, as these same old dinosaurs are paraded in front of us in these days. For example, 986 Best Picture, Ollie Stone's "Platoon": Two Sgts, polar opposites. Alias is the peacey pot smoking genius, plant lover, bandanna wearer and banana eater. Barnes his corollary, and kepplerian twin is a machine built by pain and overcoming of it "pain is weakness leaving the body" as he and his friends would say. NOTE: These two archetypes exist in all military applications.
