Other mistake: During this episode, Trapper and Hawkeye keep switching Frank's pistol with other things. When Frank's training his South Korean platoon, Trapper, Hawkeye, and Radar show up all decked out, and while Hawkeye's telling Frank that using the anti-aircraft gun on the compound will draw enemy planes, etc., there's a pistol in Frank's holster. When Frank turns around, we see that Trapper's right arm is bent over his fly swatter the entire time until he steps away from Frank, and when Frank draws from the holster what he believes is the pistol, he pulls out a plunger, and although it's funny, Trapper never actually had the opportunity to switch the pistol with the plunger, nor did Hawkeye or Radar.
Revealing mistake: When Charlie drops the bomb on the General's jeep it is obvious that the jeep is already burnt and mangled when the explosion starts. (00:14:15)
Continuity mistake: When Hawkeye hits on the nurse after Charlie's first flyover, his beach chair instantly folds itself up. (00:06:40)
Factual error: Out by The Gun, Hawkeye's Captain insignia on his garrison cap is missing the lower corner of one bar. So, it would be considered unserviceable, that is, unfit for use, and should have been replaced with a new insignia.
Continuity mistake: In Henry's office, Burns tosses the stapler toward Radar, and it flips midair. When it falls Ito the file Radar has, it flies level, that is, not twisting in the air.
Continuity mistake: As Hawkeye and Trapper leave the Swamp to watch 5 O'Clock Charlie, Hawkeye is carrying a folding chair, and Trapper has the thermos and glasses. At the show, they both have folding chairs.
Audio problem: As Radar sets the clock back to 4:30, you hear ticking. The clock is electric, and wouldn't make a noise like that.
Continuity mistake: As Radar turns from Henry's desk, the tote board he has under his arm disappears as he approaches the file cabinet.
Continuity mistake: As Frank and Henry sit at Henry's desk, and Henry is holding his doll, the cigar he has goes from his mouth to hand and back again.
Factual error: General Clayton is wearing ribbons on his regular fatigues. This is incorrect as the ribbons would only be displayed on the dress uniforms. Only the officer's rank would be on the fatigues.
Continuity mistake: As Hawkeye goes to leave the Swamp, the club he's holding goes from the top of the grip an inch or so above his fist, to the top in his palm.
Continuity mistake: Frank comes over to talk to Hawkeye and Trapper. His arms go from down by his sides to hands on hips between angles.
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 Margret puts The Gun belt around Frank's waist, it is twisted in the back. After the cut, it is righted. (00:02:30)
Continuity mistake: When Hot Lips calls General Clayton to her tent, he closes the door twice. (00:11:45)
