I was watching a program about the US Marines on the Military Channel the other day and something caught my eye. They showed clips from some amphibious landing in the Pacific, maybe Iwo Jima, and several of the Marines had what looked like blue paint on their faces. Was this just because the film wasn't originally in color or what? Are my 32 year old eyes decieving me? I noticed it on a couple of guys in a landing craft and on one guy hunkered down on the beach. Was this camo paint or bug repellant? Any info would be great.
