About Colonel Carmichael[]
In "The Novocaine Mutiny", Frank has brought Hawkeye up on charges of mutiny, alleging that during the time when Potter was away and Frank was in temporary command of the 4077th in October 1952, Hawkeye had hit him and took over command illegally.
In accordance with Article 32 of the Uniform Code of Military Justice, Colonel Carmichael conducts a preliminary hearing to determine if a court-martial is merited by the facts of the case.
He hears background testimony from Potter and Radar, and then Frank and Hawkeye who give conflicting accounts of what actually happened. After hearing the evidence, Carmichael concludes that no case of mutiny exists and will advise the charges be dropped. He says that he considers Hawkeye a top-flight surgeon whereas Frank, if he had not been drafted as a surgeon, would probably have been assigned as a pastry chef!
