Radar states that the other hand radio is back at the 4077th and does not work. Then, it turns up on the bus working fine.

The sub-machine gun that Frank is holding while guarding the prisoner is a MP 40. The MP 40 was used by Germany in the Second World War. Captured German ordinance would not have been used by American GIs in Korea. If Frank were to have had a sub-machine gun it would have either been a M3 Grease Gun, a Thompson Submachine Gun, or a M2 Carbine (all of which were American issue in both World War II and Korea) But more likely, any weapons these doctors would have had would have been either M1 Garand or a M1 Carbine.

When the Korean is surrendering, it is apparent by the sound that the scene was shot indoors.

The chocolate bars shown are not of the type issued to GIs in the Korean theatre, Standard milk chocolate was found to melt far too easily and so the United States Army turned to Hershey for help in developing its survival Field Ration D bar, it was only natural that in 1943, the Procurement Division of the United States Army approached Hershey Chocolate Corporation about the possibility of developing a heat resistant confectionery chocolate bar with an improved flavor. After a short period of experimentation, Hershey's Tropical Chocolate Bar, in one and two ounce sizes, was added to the list of war production items. The label was a type of glassine paper, white or tan, printed with brown ink with the exception of the word "Tropical" which was printed in red.

Hershey's Tropical Chocolate bars were developed to provide military personnel with access to a confectionery treat in parts of the world where Hershey's traditional products would readily melt. The Tropical bar's product formula was designed to allow the bar to hold its shape after one hour in 120 degrees Fahrenheit.

This bar was destined to exceed all other items in tonnage produced and along with the Field Ration D bar, became part of Hershey Chocolate's history. By the end of World War II, almost 380,000,000 two ounce Tropical bars had been produced for the United States military.

The armistice ending the hostilities of the Korean War took effect in July of 1953. The bus used in this episode, as well as several others, is a 1954 Ford which would not have been in production at the time depicted.

With all four of the 4077th's regular surgeons attending the medical conference, it is not explained who would be around to attend to the wounded back at camp.

When Frank is trying to use the radio to contact help, Potter tells him that the other radio is 20 miles away. If they are lost, Potter would have no idea about distance.
