Visible crew/equipment: At the end, after Father Mulcahy says goodbye to Sarah, when it cuts to a wideshot we can see two actors' rubber T-marks on the ground. The first is behind Father Mulcahy's feet, a white T-mark (albeit dirty) where Sarah had been standing, and the second becomes visible when Klinger runs over and bumps into Kellye, he kicks up some dirt which causes the black rubber T-mark to flip up off the ground.
Visible crew/equipment: After Radar walks into the Swamp and gives Hawkeye and Trapper the coffee and case folders, just as Radar tells them that he was too sleepy he walks out, and the actor's chalk T-mark can be seen on the ground (although faint, it's distinguishable).
Visible crew/equipment: When Klinger wakes up in post-op, Margaret, Hawkeye, and BJ are happy he's awake, and in Klinger's first close-up when he asks about Weston the shadow of the boom mic can be seen at the top left corner of the screen, and in his second close-up a bit of that shadow is still noticeable as it moves out of shot.
Continuity mistake: When Klinger's stopped by the MPs it cuts to a close-up of the Polaroid camera and it's lying between the seats with its hand strap facing the front of the jeep, but when Klinger picks it up the camera's positioned the opposite way with its hand strap facing the back of the jeep.
Continuity mistake: While Colonel Potter is painting the portrait of Charles, the portable military field desks behind Potter are all open - note the front doors are flipped down, but in the closeup of Charles holding the painting of himself the doors are folded up. And the books, etc. atop the field desks change as well.
Continuity mistake: While Charles is reading the letter about his nephew being discharged because of fainting spells, Klinger feigns a fainting spell falling forward onto Hawkeye's cot, and his body lies lopsided with his leg hanging off, but when it cuts to the next shot Klinger's perfectly positioned on the cot. Also, note the mail Klinger tossed earlier onto Hawkeye's cot, near his pillow, is now neatly tucked under the blanket towards the foot of the cot.
Continuity mistake: While Charles, BJ, and Hawkeye are in the Officers' Club, when Margaret storms in and starts yelling at Charles about the visiting pervert Colonel, Charles facepalms himself with his right hand, but next shot his left hand is up, and it continues to switch.
Visible crew/equipment: While BJ, Hawkeye, and Charles are in the Swamp, when BJ starts reading the letter from the child who thinks the army is like camping out Charles takes that letter away from BJ, and just as Charles is about to sit back down the edge of the Swamp set can be seen at the top right corner of the screen.
Visible crew/equipment: When Sidney arrives and speaks with Klinger in the office the door remains open for the next few shots, and while Klinger first talks to the doctor and then to the driver, we can see the top of the crooked "sky" backdrop behind the tent in the compound.
