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.
Visible crew/equipment: As Col. Whiteman leave Sentry Post 1, where Klinger is, the boom mike is reflected on his helmet.
Continuity mistake: After Frank switches pearls, he gets out of the tent and the door and it closes. A moment later, he's crawling out the door again.
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)
White Gold - S3-E23
Continuity mistake: As the men are sneaking by the tents, Hawkeye's voice is heard coming from a tent with opaque windows. A minute later in all the commotion, he's seen coming out of the Swamp.
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)
Factual error: When reminiscing about Radar's appendectomy, Henry says it took a long time to find because it was behind his secum. The appendix is behind the secum in more than 50% of people, so this shouldn't have fooled a doctor of Henry's caliber. (00:09:00)
Continuity mistake: When Henry kisses Margret, she grabs her hat. In the reverse shot, her hand is around Henry's neck. After the next cut, it's on her hat again. (00:20:00)
Continuity mistake: In one of the earlier episodes Henry becomes the father of a baby boy; his other two children have been established as Molly and Janey, both girls. In "Abyssinia Henry," Henry get his discharge papers and wanted to call home with the good news. He tells Radar that he will have to wait a while, as his son, Andrew, will be practising his trombone. As Henry only has one son, Andrew has to be the son who was born while Henry was in Korea. Even if Henry was in Korea from the very first days of the war, by the time he left his son can't be any older than 18 months - hardly likely to be playing a trombone.
Continuity mistake: When Radar and Burns leave the tent for morning parade, Radar's clipboard acquires a pencil. (00:02:50)
Audio problem: When the soldiers in the back come flying through the window, you hear a window pane break and cullets tingle when the window is in fact a Japanese-style paper window. (00:43:40)
Continuity mistake: During the shelling on the road, BJ gets very muddy. When they get to the bar, he is much cleaner - e.g. all the mud has disappeared from his right arm. (00:44:30)
Visible crew/equipment: When Frank climbs into the jeep belonging to Major General Cornell Dickering, the MPs show up at the same time that BJ and Hawkeye walk up to join the fun, and during this scene there's a T-mark (albeit a dusty one) on the ground at the driver's side of the jeep.
Continuity mistake: When Hawkeye and Radar leave the 4077 in the jeep, the last three numbers on the hood are "717" but when they get to Kimpo it's a different serial number ending in "388."
Continuity mistake: When Radar and Hawkeye leave the 4077, the jeep they're in has its windshield in the fold-down position over the hood, but in the two shots from behind Hawkeye and Radar when they see the checkpoint up ahead and Hawkeye speeds up, the windshield has vanished and there's a star on the hood.
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).
