Continuity mistake: After Klinger throws his ball, his arm stays extended outward. As the shot cuts, looking down the lane towards him, his arm is hanging straight down. Then, after the strike, he raises both arms up. A second later, his left arm is down by his side, his right doing a celebratory motion.
Revealing mistake: During the conversation between Potter and Klinger in the Mess tent, if you look past them you can see Margaret loitering, waiting for her cue to enter.
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.
Continuity mistake: As Potter says "knowing mademoiselles in the war, P.M." (pre Mildred) his hands are by his drink. As he finishes his line, they're crossed on the table.
Continuity mistake: When Hawkeye gets into the chow line and Igor suggests the peas and carrots, Hawkeye asks about the beans. As the peas and carrots are being scooped to be served to Hawkeye, he grabs Igor's arm and peas and carrots are spilled into the beans. Peas are VERY visible in the beans. The next shot with the beans, the peas and carrots have been removed from the beans.
Continuity mistake: After Klinger's file cabinet gets bombed, BJ appears in the window. He's facing directly ahead, head slightly tilted to the right. When the camera goes to a close up, he's in quarter profile, left cheek forward. In the long shot, he's back to the original position.
Continuity mistake: After the files blow up, Klinger sees BJ looking at them. If you look carefully, you see that his head changes position between shots.
Continuity mistake: When BJ is letting Hawkeye in on the fact the he was the only real victim of the gag, he's putting a forkful of eggs in his mouth. After the camera cuts to Margaret and back, he doing it again. His mouth was empty both times.
Continuity mistake: When filming Hawkeye, BJ and Charles in the swamp before they go to Potter's tent, the camera has a clear, unobstructed view of the inside. When it pulls back you can see the end of the tent, but without the netting normally there.
Continuity mistake: When BJ comes out of the building and meets Paul, you can see a chain-link fence in the background that you never see any other time in the series.
Bombshells - S11-E6
Character mistake: When the band is playing "Hooray for Hollywood", the conductor's beat pattern is backward: up-down instead of down-up.
Continuity mistake: As Hawkeye makes his offer, Frankenheimer is sitting with his hands clasped. He starts to unclasp his hands and put them on the chair arms to stand. When the scene shifts to him alone in frame, his hands are clasped again.
U.N., the Night and the Music - S11-E10
Continuity mistake: When Col. Potter runs out of his tent to say goodbye to Capt. Lal, he wears only one slipper. When the jeep drives away and Potter's feet once more are visible, both feet are in slippers. (00:22:05)
Continuity mistake: In the beginning scene in the mess hall, Charles' rank insignia & medical insignia are on the wrong sides of his collar, the next scene they are on the correct side.
Factual error: During this episode, Sergent Klinger gives a Hershey Chocolate Bar with Almonds (although the 'Hershey' name is obliterated on the bulk box as well as the bar itself, there is no doubt as to what it is) to a wounded North Korean soldier, who accepts it and turns it upside down, revealing a Universal Product Code bar code. Bar codes were not used on products until some 20 years later. (00:12:20)
Visible crew/equipment: While Kilnger's guarding Soon-Lee, when Father Mulcahy walks into the tent the shadow of the boom mic dips into view at the top, left side of the screen.
Visible crew/equipment: In the Swamp, when Houlihan shouts, "I'll be back and you better come up with something," the moving shadow of the boom mic can be seen at the top, left side of the screen.
Goodbye, Farewell, and Amen - S11-E16
Continuity mistake: When the injured tank driver appears in the open hatch while Margaret's yelling at him, he does not have a bushy mustache, but in the next shot in the OR we hear Margaret telling Potter about the tank driver while they're operating on him, and when the camera pulls in closer we see that he has a big bushy mustache. (00:10:50)
Goodbye, Farewell, and Amen - S11-E16
Continuity mistake: After Klinger presses Potter about getting rid of the tank Potter tells Klinger to act like a sergeant, and in the shot from Potter's office Klinger walks out with both of his helmet straps hanging loose, but when it cuts to him walking into the outer office one of the straps is suddenly gone. (00:33:45)
Goodbye, Farewell, and Amen - S11-E16
Visible crew/equipment: While Klinger is on the phone trying to set up BJ's transportation home, just as Winchester walks into the office pointing out the company clerk the shadow of the moving boom can be seen on the wall, and it's also visible when Winchester takes the mailbag and dumps the contents. (00:42:50)
Answer: It is actually Cencompac for Central Command of the Pacific. It is like the headquarters for all military activity in the Pacific Region (Japan, Korea, Okinawa, etc. The newer version of that is United States Pacific Command (USPACOM).
EMTurbo
And the abbreviations were used mainly by the Navy. Especially CENCOMPAC.
