Character mistake: During The Interview in the Officer's Club, after Rizzo gets the West Point question wrong, Charles dismisses him by saying, "Thank you, Corporal, that'll be all." Rizzo is a Staff Sergeant (SSG) according to his sleeve.

Continuity mistake: In the Swamp, after another drink, Charles puts a clamp on BJ's hand. As he does, the points are facing Hawkeye. In the wide shot, they're pointing at BJ. Then after Charles passes out, they're pointed at Hawkeye again.
Visible crew/equipment: In the kitchen, as Klinger and Winchester banter back and forth, the shadow of the boom mic can be seen in the upper right corner of the shot.
Factual error: When Winchester is shown in the Post Op, his oak leaf and medical symbols are on the wrong lapels.
Follies of the Living - Concerns of the Dead - S10-E10
Continuity mistake: When BJ, Charles, and Hawkeye are in the Swamp getting drunk they toast to "war, the fountain of loveliness," and Charles attaches the surgical clamp to BJ's hand and it dangles with the end facing out in the closeup, but the clamp faces the opposite way in the wideshot, then it's changed again.
Communication Breakdown - S10-E6
Continuity mistake: When Charles leaves the shower with newspaper covering his privates, the newspaper at his backside is wrinkled and messed up when he enters the Swamp in the exterior shot, but next shot the papers are different and arranged neatly.
Continuity mistake: In the Swamp, as Hawkeye asks about Peg's cookies, BJ folds the cards in his hand, and places his left hand over the top. In the close up, as he answers, he suddenly has the cards back in a fan.

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.
'Twas the Day After Christmas - S10-E9

Continuity mistake: In Potter's tent, he holds the door for Brandy to enter. In the close up, you see him drop his left hand to close the door after she passes him and inside. After the angle change, his hand is back on the door, and she's just even with him walking forward.
Where There's a Will, There's a War - S10-E16

When the shelling starts, all the boxes in two of the stacks fall off the table, leaving one stack. When the shot changes, there are suddenly two stacks of boxes on the table.
Plot hole: In this episode, Margaret is required to give a lecture on the use of Levophed, because it is being introduced. However, in the Episode "Period of Adjustment"(8-6), Hawkeye orders an IV of Levophed for one of his patients. (00:12:15)
Other mistake: When the scene is of the cow in the barn, the background hilly area can be a painted backdrop.
