Other mistake: Looking at the pins when Margaret bowls at the end, the 5 pin slides backwards towards the camera, but not fast enough to bounce off anything and then fly in from off screen. Granted this was done in slow motion, but the physics don't seem to add up.
Other mistake: When Trapper and Hawkeye are driving along, you can see two points of light on the steering wheel. The lights are from from the filming illumination panels.
Other mistake: When Trapper and Hawkeye make the right turn after Trapper tries to use the restroom, you see that Trapper avoids the left side of the road just after the turn. This is to avoid the explosive charge set in the ground used to simulate a mortar round exploding.
Other mistake: Rosie says she took the darts away from Klinger and BJ, but there are still plenty of darts sticking in and around the dartboard. (00:12:45)
Goodbye, Farewell, and Amen - S11-E16
Other mistake: When Hawkeye drives the damaged tank out of the camp, the front MG is missing. There's not a mark on the armor surrounding the MG port that might suggest it was destroyed in battle. Why would a tank in combat just be missing one of its MGs?
Other mistake: In the episode where Radar is talking to Corporal Hendrix, Radar says that he was thinking about getting a tattoo himself. But in season 3 episode 7 when Col. Blake was giving Radar his physical he had an anchor on his right arm which he said was his new tattoo. (00:08:20)
Other mistake: Charles starts a discussion on the army having forbidden the use of curare. The following chatter is all about how things in the M.A.S.H. OR have slowed after curare was banned, leaving us with no choice but to understand that the ban came into effect during the Korean War. Actually, curare was not approved for use by the U.S. Army at any time during the Korean War. (See "Notable Names in Anasthesia" - J. Roger Maltby, Royal Society of Medicine, Great Britain, pg. 14). (00:00:25)
Suggested correction: The whole point of the discussion is to make it clear that curare was never allowed for use by the US military, however since the majority of the doctors there are not enlisted, they know of curare and how to use it on a patient. At no point is it mentioned that the banned occurred during the Korean war.
While they never specifically say that the ban occurred during the Korean war, at the beginning of the episode, Charles says "Ever since the army forbade our use of curare..." Then at the end of the episode, COL Potter says "It sure is the cat's P.J.s having our curare back." after they get some supply from another non-American unit. These conversations imply that the doctors had been allowed to use curare by the army until this point and the ban by the army is why they aren't using it any more.
Father Mulchahy says "I've noticed the work goes much faster with curare." Father Mulchahy's only experiences in operating rooms are from his deployment at mash 4077 (he mentions he used to work with children before the war), so he must have "noticed" it there. This makes it clear as daylight that curare was used at mash before it was banned.
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)
Other mistake: When the scene is of the cow in the barn, the background hilly area can be a painted backdrop.
Cementing Relationships - S9-E3
Other mistake: When the mistake in the cement is discovered, Klinger is addressing Pierce, saying "Mr. Putty Putty, here." Problem is, that it was Mulcahy singing, "Cement mixer, putty putty.
Other mistake: When Penobscot is approaching the group, you can make out "4077 USA MASH" on the bumper, even though the the numbers and MASH are partially obscured.
Other mistake: As Burns, driving the tank, runs over the Swamp, there's no sign of the still anywhere.
Other mistake: While playing golf, something blows up Henry's golf ball. When the camera does a closeup on Henry's ball, you can see that it isn't a golf ball, but a prop designed to blow up.
Other mistake: As Hawkeye sings in the Swamp to mock Frank, watch Trapper. He's miming the words until his cue to join in.
The Abduction of Margaret Houlihan - S5-E6
Other mistake: As Frank cocks his gun in the Swamp, the slide locks open and he has to hit the slide release to get it to move forward. Next he fiddles with the hammer. Next we hear the shot go off. Burns' excuse later is that he was cleaning The Gun and it went off (although admittedly, Frank doesn't always stick to the truth that religiously in situations like that). The slide on a semi-automatic locks open only if the magazine is empty or missing. The Gun locking open is also a clear, unmistakable indication that the breech is empty. He would have to insert a filled mag, then pull the slide back again to chamber a round before The Gun even had the chance to go off. One never does that while cleaning a gun. One does what Frank did to begin with: Pull the slide back without a magazine inserted to make sure the breech is empty.
Suggested correction: Frank has demonstrated on numerous occasions that he does not follow the rules of safe gun handling, so ascribing his failure to do so is not a mistake.
You are missing the point. His gun is demonstrably unloaded when we last see it. He would either have to change his mind about cleaning it and load it instead, or load it first and then try to clean it (which makes even less sense), neither of which is not supported by anything in the dialogue.
Other mistake: In all the opening sequence of each episode, a group of people are waiting on the pad to get the wounded off the choppers. If you look closely as the group goes to move, the character Mulcahy is there, but it's George Morgan, who played the role in the pilot episode. From the third episode on, it was played by William Christopher, so it's the wrong actor for all the other episodes.
Other mistake: Hawkeye reads the propaganda flyer, he says. "Give yourselves up, you can't win. Douglas MacArthur." Trouble is, the papers are all advertising for a flying company called Ace Eli.
Other mistake: In this episode Max is wearing a red bandanna that he says "My mom gave me this when I shipped out. She said never take it off." However, in no episode before or after this does this good luck charm appear.
Other mistake: Hawkeye loosened the nut and locking ring, but after lifting the assembly, it was obvious that these were steps used only to heighten tension. There was no locking device of any kind between the tail and body of the bomb.
Other mistake: After Klinger gives the long johns to Mulcahy, he "disappears." But if you look closely through the camo net, you can see him in the shadows of the background.
Suggested correction: Rosie said she took them away AFTER they began throwing them at the dartboard. Therefore there would be some in and around the dartboard. And since Klinger and BJ were drunk, they likely wouldn't have thought to grab them from the board.
When we later see them in Col. Potter's office, they are quite capable of semi-coherent reasoning, so them not realizing they could grab more darts from the dartboard isn't really in sync with that later behoviour.
