Continuity: When Radar and Burns leave the tent for morning parade, Radar's clipboard acquires a pencil.

Continuity: When Hawkeye is examining the orphan who is wiggling his tongue, there are two camera angles: one of Hawkeye from the front and one of the orphan over Hawkeye's shoulder.

Factual error: Radar is seen sleeping holding an Avengers comic which was not published until several years after the Korean war ended.
