It was originally just the Indy head on the Henry Jones body with age lines and weathering on the face and a simple paint job, but I eventually went back and modified the torso to find on some GI Joe style legs so he's fit in better and get some height.
Originally, I thought perhaps President Ryan was the one who put together my Sally Squad team... but I've since decided it was President Steve Rogers, aka Captain America.
While I envision him to be based on Harrison Ford's portrayal of Jack Ryan from the "Clancy-verse", my brother insists he's the President from "Air Force One."
