M! Garand, The m1 sakinaw actually it's a Saginaw (carbine already field tested and used by the Raiders and Paramarines), The Thompkins um that would be a THompson (I don't know about that magazine clip/maybe), and the M50 which replaces the Tommy Gun the m50, especially with the folding stock does look like a carbine. the m3 replaces/supplements the THompson color] (was issued to the 1st in New Zealand prior to Gaudal...guess it can look like an M1 carbine, from a movie point)
One point I thought rediculous was when those Bozo's decided to go to the shore and watch the Japanese ships off shore...Who by the way were looking right back at them and saying in Japanese "look at those Bozo's on the beach".
