Factual error: Amongst Radar's comics are several not published until after the end of the Korean War, including issues of The Avengers and Spider Man.
Factual error: After Radar asks Klinger when his home movies will be ready, Max answers, "Ready whenever you are, C.B." This is the specific punch line to a joke that relates to the actual filming of Cecil B. DeMille's 1956 movie The Ten Commandments, which wasn't released until after the Korean War. (00:16:30)
Factual error: When the South Korean Colonel and General are in the mess tent, their rank insignia are wrong. The insignia they are wearing are for the U.S. Army.
Suggested correction: They could have been Korean Augmentation To the United States Army (KATUSA) officers, who were Koreans drafted or volunteered into the US military to act as a liaison between Koreans and the US military. As such they wore US uniforms and rank.
Factual error: Nearing the end of the show, we are told that the Chinese have become involved in the conflict and have attacked with some 300,000 soldiers. This apparently refers to massive attacks by the Chinese starting on November 1, 1950. Although the numbers are correct, the US/UN forces were unaware of the numbers. As late as November 6, the Far East Command continued to insist that there were no more than 34,500 Chinese communist soldiers in country. http://www.history.army.mil/brochures/kw-chinter/chinter.htm.
Factual error: When the can of beans explodes all over Hawkeye and Hotlips, they act as though the beans are cold. In fact the beans would have been at boiling temperature as the can overheated, causing it to explode, and the two would have been burned.
Factual error: In the hut with BJ, Zale, and The Moose, there's a Coleman 413E stove in the background. Trouble is, that this unit didn't appear until 1954, and the Armistice ending hostilities, ending the war, was signed July 27, 1953.
Factual error: When the South Korean Colonel and General are in the Mess Tent with BJ, their rank insignia is wrong. The insignia the Colonel is wearing is for a U.S. Colonel, and the General's insignia would not be three stars in a horizontal line.
Factual error: As Hawkeye, Radar' and BJ stop to change the flat, Hawkeye uses a scissor jack to raise the Jeep. However, the scissor jack was not in use for this model of Jeep.
