Character mistake: When Henry is describing the fishing reel he bought for his girlfriend, he said, "with jeweled escarpment" actually it is a 'jeweled esCAPEment" not esCARPment. An escarpment is a long slope off a plateau. An escapement is a latch/release mechanism that you would find on a device like a fishing reel.
Goodbye, Farewell, and Amen - S11-E16
Other mistake: How did Hawkeye Pierce, a surgeon, know how to drive a tank? It is nothing like driving a car and takes skills, training and experience that a surgeon simply would not have. He wouldn't even be able to start the engine.
Aid Station - S3-E19
Factual error: Mulcahy asks Hawkeye if he trusts God. Hawkeye replies "It says I should on all of my money." However, the phrase "IN GOD WE TRUST" didn't appear on American bills until 1957.
Good-Bye Radar: Part 2 - S8-E5
Other mistake: When Potter enters the Swamp, his rank insignia is placed wrongly, with the feet of the eagle pointing to the front of the collar. The feet should point toward the shoulder side of the collar, as they are the next time we see Potter.
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.
Factual error: Throughout the series, there are repeated instances of "I Corps" being pronounced, "Eye Corps." Since Army corps are designated by Roman numerals, it should be pronounced, "First Corps." (I wonder how they would have pronounced "III Corps" or "XVII Corps?").
Aid Station - S3-E19
Other mistake: After Hawkeye gets back from Aid Station, Trapper is making a cup of tea. When he tries to hang the tea bag on a nail on the tent post, it unwinds and falls to the floor.
Suggested correction: This isn't a mistake, especially since we don't see it hanging back up in another continuous shot.
The Sniper - S2-E10
Continuity mistake: When Hawkeye is preparing to go for his picnic, Radar brings him some brandy from Col. Blake. There is only a small amount of brandy in the bottle, which is commented on. Radar takes a jug of martini from the still to top up the bottle, but this is not done and the jug of martini remains on top of the stove untouched. When the picnic scene takes place, the brandy bottle is now nearly full with the brandy/martini mix. (00:10:00)
Character mistake: In the opening scene, Hawkeye and Trapper are operating on a two-star general. But neither one of them or the nurse is wearing their masks. They are under their chins.
Continuity mistake: When Klinger imposes himself between Oksun Li and Crosetti, he puts his hands on his hips. When Crosetti gets up, Klinger gestures with his hands which then drop down on either side. A split-second later they're on his hips again.
The Late Captain Pierce - S4-E4
Other mistake: When Digger shows Hawkeye the copy of the death certificate, Hawkeye steps out of the shower stall and its door swings back and forth. As Hawkeye wipes his face with the towel, we can see the top of the flesh colored covering Hawkeye is wearing. (00:08:05)
Goodbye, Farewell, and Amen - S11-E16
Continuity mistake: When Hawkeye is returning to camp, he and his driver completely pass some Burma-Shave signs the other have set up to welcome him back. An ambulance bus is a few feet behind them and manages to then suddenly appear at least 30 feet behind them to smash all the signs.
Factual error: Radar's mother's boyfriend owns a Nash Metropolitan, a car that was not produced until after the end of the Korean War.
Continuity mistake: In one episode, Frank's middle initial is M, then later it's D. His full name was Franklin Delano Marion Burns.
Audio problem: As Roy and Loraine enter the camp, you hear a "YEE-HAW" from Roy, but if you watch his mouth, you see he really says "YAHOO."
Preventative Medicine - S7-E22
Continuity mistake: In Potter's quarters Klinger's arm holding the chicken goes from in front of his chest to by his waist between shots.
Factual error: The Spot-A-Card pinball machine in the Officers' Club didn't come out until the 60's.
