Continuity mistake: When Father Mulcahy's finishing up his Sunday service with only Klinger, who's wearing a fetching red hat, there are nine stacked books at the corner of the table, but when it cuts to Mulcahy's closeup there are now only six stacked books (which will soon be used for the 11:00 Protestant service when Trapper and Hawkeye will pray for booze).
Continuity mistake: Frank hits the pole supporting the center of the tent, which lets the tent collapse. However, in later episodes, the tents, especially hers, has a sturdy wood frame and doesn't need a center pole.
Continuity mistake: When the two soldiers get into a brawl in Post-Op, it's daytime. When Potter talks to Mulcahy, it's night. Then Klinger tells Mulcahy he's needed to break up the fight, it's daytime again.
Suggested correction: In scene 1, set in the day, the Greek soldier is wearing a dark blue jacket and a light blue shirt. In scene 2, set at night, Father Mulcahy is wearing a black shirt and a brown robe, and resting before bed. In scene 3, set during the day, Father Mulcahy is wearing a black shirt, a sweatshirt, and a baseball cap. He is punching a speed bag. Klinger says there has been another fight between the Greek and the Turk. The Greek is not wearing a jacket. Scene 3 is from a different day than Scene 1.
Continuity mistake: In the Commander's office, Frank's arms go from being in front of MacArthur's picture frame, to gone, and back again in a matter of a few seconds.

Continuity mistake: As he addresses Maj. "Chicken Lover", Lt. Smith's head goes from leaning left to leaning right between shots.
Continuity mistake: When Blake is talking to Burns, he sits and plays with his doll, which is facing toward the office door. After the angle change, the doll is facing Henry.
Continuity mistake: When the General comes up, Pierce and Trapper are walking away toward the camera's left. When Pierce calls for the General's attention he is shown gesturing to the open door. Problem is, that they should be looking over their left, not right, shoulders, and we should see the inside, not outside, of the door.
Continuity mistake: While talking to Hildebrandt, Henry smacks his hands together while saying "Gee, whiz!" When the angle changes, his hands are on the desk.
Continuity mistake: When Frank inspects the local workers, the laundry woman bends down to help the kid put away the sandwich Burns suspected of being a bomb. After the cut, she's upright again. (00:10:45)
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.
