Factual error: In this episode, the regulars receive and respond to letters from a Fourth-Grade class in Hawkeye's home town. Charles receives one from a little girl who says she's sent him a birch leaf. Unfortunately, the leaf he removes from her glassine envelope is a maple leaf. (Note: there was no indication that this was supposed to be her mistake.)
New this month Factual error: Unless the regulations for the time period were different, the belt buckles seen with the regular fatigues is incorrect. They should be the same color as the belt and/or uniform. The brass buckles seen were used with the dress uniforms only. Also, any rank insignia worn by officers would have been dull in color so that they would be less of a target to snipers.
