At the end of this episode, where Radar is sunbathing, notice the Jeep that Col. Potter drives up in. It is a CJ-5 model, which was built from 1955 - 1983, and therefore could not have been present during the Korean conflict. It is easily recognizable by the "rounded" front fenders, rather than the "flat" fenders used on the military jeeps of the time. Also, the Jeep has a glossy paint job, rather than the correct flat O.D. paint.
