The point system was used in Korea. In Sept. of 1951 the Army stated that an officer needed 55 points to be rotated home. They revised this in 1952 to state that it would take an officer 37 points, (not 36). This reduction was not followed up by an increase. This is the inaccuracy. Considering the amount of time that Hawkeye spent in Korea, he probably would have been rotated home in season 5 or 6.
The Panmunjon Peace Talks are featured in this episode - but they have already taken place, since they are mentioned in "Dear Mildred" (Season 4).
B.J. is shown wearing a shirt that has been dyed red. They don't dye the uniforms red until the next episode, "Peace On Us".
Charles makes the statement that his sister Honoria eloped with a farmer, and then abandoned him and started living with a shoe salesman. In the very next episode, he will mention an incident that took place during his sister's wedding. In a later episode, Charles will get bent out of shape because his sister plans to marry an Italian.
Hawkeye is afraid of mice in this episode. He hasn't been in previous episodes, nor has he been afraid of rats. Isn't it a bit odd that he is scared of mice but not rats?
When BJ and Hawkeye are in the Swamp, BJ's scarf is hanging down, in the next shot it is over his shoulder and in the third shot it's again hanging down.
Apparent film flip: In the close-up shot of Dupree sitting on the bunk, talking to B.J. and Charles about riding "Sophie," his collar insignia are on the wrong sides. As he entered the tent and before sitting, then after rising from the bunk to leave the tent, the insignia are on the correct sides.
Lorraine Anderson makes a big deal about the fact that Margaret allowed her pierced ears to close up--but Lorraine did, as well. There's no sign of earrings or holes in her ears, and she makes the suggestion that "we" re-pierce "our" ears. (And use Donald's medals to make earrings.)
Discrepancy in background: In the series pilot episode, Hawkeye tells Trapper John that Ho Jon can stay with his parents while attending medical school in the United States. In this episode, however, he tells Radar that his father is a widower (and relates a story about an event involving his widowed father which happened when he was 12 years old), which is a discrepancy in his personal history.
Radar talks about the "new" Nash Metropolitan. This car was introduced in UK and USA in March 1954, some time after the Armistice.
Private Harker needed type AB negative blood. Why didn't they get it from Winchester instead of having to search around and wait for a drunk bomb disposer? In "Life Time" from Season 8, we found out Winchester is type AB negative.
BJ incorrectly identifies the title of a musical composition that Radar is playing during surgery as "Musical Clock." The actual title of the piece is "The Syncopated Clock," by the noted American composer Leroy Anderson. BJ is correct, however, about the use of the piece; it was used as the theme for both The Late Show and The Late, Late Show on WCBS-TV, which, in the 1950's & '60's - before David Letterman and Conan O'Brien - aired old movies after the late news every night.
When Mulcahy tries to tell Potter about the penicillin, you can see that the close-up of each man were shot at different times. When we see Potter's face, Mulcahy's shadow does not reach Potter's shoulder but when we see Mulcahy over Potter's shoulder, he is casting a definite shadow over his shoulder and beyond.
Margaret mentions this vascular clamp in Ep. # 133, "Comrades in Arms Part II". This was three episodes prior to this one. However, this episode (Y-114) was created previous to 132-133 (Y-116, Y117), so the error lays within the scheduling of airing the episodes.
Charles refers to the Korean who re-builds his horn as "Sang Mu," but in the closing credits, his name is given as "Sang Nu."
After Colonel Potter talks Saunders out of commiting suicide with the gas mask in the OR, he never turns off the gas before they leave the OR.
When Charles is winning, he decides to leave the table for a break. When he scoops his chips into his box, he also scoops the cards.
Charles says, "It's a semi-free country." The show's writers are being slightly repetitive; Hawkeye said the same thing during the earlier episode "Welcome To Korea."
When Margaret and Hawkeye wake up cuddling, their dialogue and body language (especially Margaret's) indicate that they did a lot more than just kiss the previous night. However, they are still completely dressed when they wake up together. Was the night cold enough that they felt they had to put their clothes back on afterwards?
When Hawkeye and Margaret are demonstrating the arterial transplant, Margaret mentions that they are using a vascular clamp that was designed at the 4077. Hawkeye and B.J. do not design this clamp for another three episodes. (Ep. # 134, "Patent 4077"). Although "Patent 4077" first aired after this episode, it was actually produced before this episode, as evident by the episodes production numbers. "Patent 4077" has a production number of Y114, whereas "Comrades In Arms Pt 1 and 2" have production numbers of Y116 and Y117.
