In his commentary, Larry Gelbart recounted that the role of the Supply Sergeant was originally played by Vic Taylor, however, this was shot again with a different actor, which is what appears in the final version. However, they forgot to change this in the credits so the credits wrongly show Vic Taylor's name.

Rizzo, the wounded soldier in post-op whose infection sparks the search for an incubator, is dressed in a t-shirt under the covers of his post-op cot. Patients, particularly those who are severely wounded, are dressed by hospital personnel in hospital gowns or pajamas with button-down fronts for easy access to the chest. They would never be outfitted in a t-shirt while recovering from surgery.

Colonel Lambert tells Drs. Pierce and McIntyre that among the items he can secure for them are 'the odd B-52.' The first B-52 entered US military service in June 1955, nearly two years after July 1953 armistice ended Korean War hostilities.

Maj. Morris tells Hawkeye and Trapper that he never made more than $10,000 a year in his life, as if that was a meager salary. In the time period during which the series takes place, a person making $10,000 a year was considered affluent.

When trying to convince LTC Blake that the 4077th needs an incubator to identify infections -- who counters that they cost "five or six hundred dollars" -- Hawkeye responds that "the war's been running for two years -- the government must be showing a profit by now." But the problem of identifying infections at a hospital is something that certainly arose almost immediately after the establishment of the 4077th, so it is completely implausible that two years would pass before Hawkeye and Trapper recognized the need for an incubator.

At his press conference Gen. Mitchell talks about Caesar's legions crossing the Alps into Spain. When his legion had crossed the Alps they would have entered Gaul (modern day France). They would have then had to cross the Pyrenees Mountains to enter Spain (called Iberia by the Romans).
