Continuity mistake: When Colonel Potter, BJ, Hawkeye, and Charles are in the changing room, Charles wants to be alone so he takes his tan jacket off the first nail on the right and leaves, but in BJ and Hawkeye's closeups the tan jacket is still hanging on that first nail, then it vanishes again.
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.
Visible crew/equipment: While Colonel Potter, Margaret, and Father Mulcahy are in the mess tent, we see that BJ and Hawkeye arrive back at camp in the jeep, and when they walk into the mess tent the curved chalk foot marks can be seen on the floor under the table, between Potter and Mulcahy.
Visible crew/equipment: When the guy from I Corps Supply lifts the flap at the back of the truck with all the boxes, just as Colonel Potter says, "Sergeant, how many of these parcels are checking into this post," the shadow of the boom mic can be seen at the top, right corner of the screen.
Visible crew/equipment: In the overhead exterior shot of the compound, when Colonel Potter calls everyone's attention to the situation regarding "crackerjack corpsman" Sergeant Hutchinson, as the shot pans out we can see the boom and the boom mic at the top left corner of the screen. Then when Margaret calls on Hutchinson to come forward, the boom mic is moving around at the top of the screen, and it's still there when Klinger rides out on Sophie.
Visible crew/equipment: After Colonel Potter tells everyone in his office that he's been asked to address them about the possibility of making the army their career, the Swamp trio laugh, and when it cuts to Margaret telling the "clowns" to keep quiet, the shadow of the boom mic bounces around at the top, right side of the screen.
Visible crew/equipment: After Hawkeye shows the photo of his father to the North Korean, when it cuts to the shot in the Officers Club just as Klinger says, "And these players you can't tell anything," the shadow of the boom mic can be seen moving at the top, right corner of the screen.
Visible crew/equipment: At the Officers' Club, after Potter and Tucker's practical joke is out of the bag and they're congratulated, when it cuts to everyone sitting at the bar, at the start of this shot the boom mic is visible at the top, left side of the screen just before it's pulled up.
