Trivia: In the home movie of Radar's family, Radar's mother is played by Gary Burghoff, who plays Radar.
Trivia: While Hawkeye, Radar, and BJ are in General Dickering's jeep, when they meet up with some GIs on the road Hawkeye asks them, "Anybody here from Maine?" and one answers that he's from Vermont, to which Hawkeye responds, "Close, but no cigar." What's funny is that earlier in the series Hawkeye has said that he's from Vermont not Maine.
Trivia: When Igor salutes Hawkeye and BJ as they enter the Post-Op, he bangs the stove, making a "Doinggg" sound. Together with the crisp parade-ground salute, it's really hilarious once you have spotted it. If you wonder whether or not it was deliberate, you can almost see Igor slipping something into his pocket as he exits. (00:04:35)
Trivia: Toward the end, as you hear clips from the characters, they show a chopper landing at an Aid Station. If you look closely, you can see the shot is re-used from the opening of the earlier episode "Smilin' Jack".
Trivia: Frank says "Give me a man when he's 28, and he's mine for life." When this episode aired, Mike Farrell (Capt. B.J. Hunnicutt) was 36.
Answer: Even an Army field hospital would have SOME weapons for self-defense if the enemy attacked. What's meant is that it's not a combat outfit, and therefore wouldn't have enough weapons to actually attack anyone. (It's also mentioned a few times that the Officer of the Watch is supposed to carry a pistol at all times, but Hawkeye refuses to do it when he's in charge and Colonels Blake and Potter don't enforce the rule).
