The General Flipped at Dawn - S3-E1
Continuity mistake: As the chopper lands on the pad, and the ambulance comes up, the pilot is as two different men when Hawkeye and Trapper approach and arrive at the chopper, meaning the landing was stock footage.
Continuity mistake: Hawkeye is in the Swamp talking with Trapper. Hawkeye leaves and walks past the tent - Trapper is not inside. (00:07:30)
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: During the inspection of arms, when Frank stands in front of the second soldier in line, the soldier's left collar is flipped up and his right collar is folded underneath his shirt in the shots facing him, but in shots facing Frank the soldier's entire collar is properly positioned.
Continuity mistake: In the office, Radar is getting ready for bed, and has taken off his shirt. When he goes to tuck in his Teddy, he suddenly has sleeves.
Continuity mistake: As Hawkeye walks past the swamp after leaving Trapper, you can see the still is missing.
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: 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.
Continuity mistake: When Trapper turns around to ask Klinger for the status about the movie's sound, a small patch of his hat becomes wet from the roof's leaking, but in the next shot, his whole hat is instantly soaked. (00:01:55)
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)
Continuity mistake: When Father Mulcahy's finishing up his Sunday service with only Klinger, who's wearing a fetching red hat, there are nine stacked books at the corner of the table, but when it cuts to Mulcahy's closeup there are now only six stacked books (which will soon be used for the 11:00 Protestant service when Trapper and Hawkeye will pray for booze).
Adam's Ribs - S3-E11
Continuity mistake: When Hawkeye throws his food in the mess tent, it lands on the tent screens behind Radar and Klinger. The food is there in the close up shots and in the wide shots it disappears.
Adam's Ribs - S3-E11
Continuity mistake: While Hawkeye leads the protest in the mess tent shouting "we want something else," there are two closeup shots of the table where Klinger and Radar are seated, and Klinger's white evening purse is missing, but in the previous and following wideshots the purse is hanging on his arm.
Adam's Ribs - S3-E11
Continuity mistake: When Hawkeye's in the mess tent holding the food tray the succotash is on the left and potatoes on the right with a space in the middle, so when Igor serves him creamed corn offscreen the corn should be between the potatoes and succotash, but when Hawkeye's having the fit and walks away from Igor, the potatoes (a higher mound) are now in the center space between corn and succotash.
Continuity mistake: The mud spots on Lt.Smith's face change from scene to scene. (00:09:45)
Continuity mistake: As Lt. LeClerq stands beside his commander, the Commander starts to look to his left, and drops his hand. When the angle changes, he drops his hand again.
Continuity mistake: The syringe the "Mad Turk" threatens Henry with alternates between fully ready to almost empty between shots.
Continuity mistake: As he addresses Maj. "Chicken Lover", Lt. Smith's head goes from leaning left to leaning right between shots.
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)
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).
