Who crewed LVT-4's? Navy? Marines? What uniforms would they wear and does anyone make those figrues or will I have to scratch-up some figures? I am talking in the Pacific, with Marines on the beach...

I am putting the Verlinden interior into the LVT-4 and want to have the engine hatches open with a crewman trying to fix it... while the other crewmen are firing Mg's and the Marines are trying to unload supplies...
