Other mistake: When they're playing poker, Hawkeye is sitting at an angle so that Sgt. Baker cannot see the earpiece that Hawkeye is wearing. However, Hawkeye sometimes turns his head enough for us to see his ear and, since the camera angle is over Baker's shoulder, Baker must have been able to see the earpiece too and realise he was being cheated. (00:13:20)
Character mistake: As Hawkeye goes to help Maj. Burns right at the end of the episode, he touches the patient with his bloody, contaminated gloves he used to work on the last patient. Such a blatant error would be anathema to any surgeon from the civilized world of the 20th century, let alone one of Hawkeye's caliber.
