Factual error: Radar gives the location of the battle as Longitude 70, Latitude 27. This means the Korean war has spread to India. (00:21:00)
Springtime - S3-E6
Factual error: Radar mentions to a nurse he's smitten with that the movie that night is "Firstborn of Godzilla." Godzilla (the movie, not the monster) wasn't released until 1954. (00:15:10)
White Gold - S3-E23
Continuity mistake: When Perkins is recaptured, Henry leaves his office with his cigar in his mouth. In the next shot, of him coming through the door again from the other side, his cigar is in his hand. (00:20:55)
Audio problem: At the end of the show, when Trapper is playing his instrument, the music does not match the movements of his hand.
Continuity mistake: The length of the chewing gum hanging from Henry's hat differs between the front and rear shots. (00:03:10)
Continuity mistake: After Iron Guts Kelly dies in Margaret's tent, Frank Burns visits Margaret, suspecting something. Frank asks why there is a general's star on her cot. In the ensuing 'back and forth' dialogue, Margaret's hair goes (in close ups) from nicely combed, to frazzled, back to nicely combed again (and in a different light).
Continuity mistake: Just after the announcement that General MacArthur is coming, Trapper puts on his sunglasses, then the shot switches to Henry walking, and in the background Trapper is putting his glasses on again.
Continuity mistake: When Henry, Trapper, and Hawkeye get into the jeep with Radar notice the style of jeep and its number is 16930382, but when they're driving to the chopper pad the style differs - things such as hood, antenna, etc, and its number is 11172419. Then when the chopper takes off the jeep's style is back to the original jeep they were in.
Visible crew/equipment: When Margaret's in her tent reading just as Hawkeye walks in to give her the physical, the chalk T-mark can be seen on the floor.
Revealing mistake: In the swamp during the movie, Frank comes up and talks to Igor, who is running the projector. Although there is a film running, there is no film on either the supply or take-up reels.
Factual error: Henry says that every Wednesday, his wife drives up Route 26 with some friends. US. Route 26 starts out in Nebraska and leads to Oregon. The closest thing that could be described as a "Route 26" would be the road leading from Princeton, IL to Dixon, IL which begins 85 miles from Bloomington. The writer probably meant Route 24, which passes about 20 miles north of Bloomington. (00:03:10)
Continuity mistake: In some shots the Spam lamb has mashed potato eyes and a carrot mouth, in others it has green grape eyes and no obvious mouth, and it keeps changing. (00:23:10)
Continuity mistake: When Radar is going to bed, he takes his shirt off and his upper body is naked. When he puts the blanket over his teddy bear you can see sleeves. Next shot, he is naked again.
Continuity mistake: In the episode Iron Guts Kelly, Col. Wardman first calls Iron Gut Kelly a Lt. General, then a Maj. General then he goes back to Lt. General.
Revealing mistake: When the tent roof caves in and the projector shorts out in a gush of water from above, you can see that actually the projector "shorts out" before the tent roof ruptures. The crew probably didn't want to risk the pyrotechnic devices getting wet. (00:02:25)
Mad Dogs and Servicemen - S3-E13
Other mistake: Hawkeye, Henry and Trapper are playing scrabble. The board is in an illegal state - in the lower right corner 'it', 'jot', 'joy' 'yearn' and 'in' are not connected to the rest of the words. Since the others call Hawkeye on his non-existant word, I'm assuming they're playing properly. (00:15:35)
Continuity mistake: During the scene which culminates in Frank declaring the camp dry the patches of water on his helmet change position. (00:05:50)
Factual error: Another premature mention of Godzilla when Col. Blake announces that night's movie, "Godzilla and the Bobby Soxer". (00:01:57)
Continuity mistake: The mud spots on Lt.Smith's face change from scene to scene. (00:09:45)
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).
