Revealing mistake: When Radar walks into the supply room, he carries four or five ammunition belts around his neck. Since he stows them in the gun bin, it has to be assumed that they are not meant to be empty. If they were only half filled each, he would still be carrying something in the area of 60-100lb. However he moves with absolutely no visible strain and tosses the belts into the gun bin with ease. Elsewhere in the series Radar is depicted as being none too strong. Clearly the magazine pouches were stuffed with something light and the effect carrying the real weight would have on Radar was overlooked.
Continuity mistake: When Hawkeye gets into the chow line and Igor suggests the peas and carrots, Hawkeye asks about the beans. As the peas and carrots are being scooped to be served to Hawkeye, he grabs Igor's arm and peas and carrots are spilled into the beans. Peas are VERY visible in the beans. The next shot with the beans, the peas and carrots have been removed from the beans.
