While Hawkeye and B.J. are helping the prisoner to walk in post-op, and B.J. says that she's walking better than they do coming home from Rosie's, Hawkeye responds, "She was only shot -- we're usually bombed." However, when Hawkeye was triaging her, he says that she was wounded with shell fragments.

When Klinger is talking to the Korean MPs it's mentioned that it's freezing but there's no visible breath coming from anyone,

When Scully first appears, the camera is zoomed out too far and a lens filter can be seen. When they zoom in on Margaret and Scully, you can see clearly through the filter.

During the final confrontation scene in the compound courtyard at night when BJ and Hawkeye are trying to sneak the Korean woman out in the truck, there is a howling wind blowing to help set the mood that it is a cold, blustery night and add to the tension. However, the trees in the background are completely still (this was shot in a studio), and neither the tents nor the people show any signs of any kind of wind.
