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.
