After Frank Burns runs over the jeep, Colonel Potter can be seen pulling his service pistol from his waist. The camera cuts to Frank inside the tank. When it cuts back to the Colonel, the pistol is not in sight and he pulls it again to shoot the jeep.
As Frank runs over the nurses' shower, the Swamp is visible several yards behind the tank. In the next shot, however, Hawkeye, BJ, Klinger, et. al. have to dive out of the Swamp as Frank runs over it. There's no way he could have turned the tank around 180 degrees and made it over to the tent in such a short amount of time.
Sergeant Kimble wears the rank insignia of an Army First Sergeant (1SG), denoted by the diamond in his chevrons. The 1SG position is administrative; as such, Sergeant Kimble would not be working in the motor pool, as Hawkeye referred to.
Soldiers, especially enlisted men, did not return home by plane. Troop movement was by boat, except for general officers, for both deployment and redeployment. Most aircraft of that era didn't have the range to cross the Pacific ocean and would have required numerous refueling stops. The aircraft of the time were smaller and carried fewer passengers than jet aircraft. This continued until 1966 in the early stages of the Vietnam war.
When BJ and Hawkeye are treating Lt. Chiver's toe, BJ notices that a microscope is missing by the outline of a layer of dust on a table. Given that they are a medical unit and everything should be as clean as possible, there shouldn't be that much dust on a table.
Pierce treats the Colonel for a probable venereal disease with a dose of intramuscular penicillin. Without microscopic examination, there would be no way to confirm the particular bacteria, and, in turn the appropriate treatment. Follow up care would also be required to ensure that the infection was indeed cleared up.
Radar and Klinger are each taking a cold shower according to the dialogue. However, steam rises from the shower.
The radios being used by those at M*A*S*H are hand cranked point-to-point radios. During this episode Radar can be seen carrying the "phone" across Col. Potter's office to Hawkeye. These radios require a wire connected a series of wires that carry an audible tone to other radios. The hand crank is what provides the audible "ringing" tone on the other end. Throughout the series, it can be noticed that the radios do not have a wire connected to them.
Potter appears to chamber a round in his .45, but the slide locks back and he has to manually release it. This indicates that the gun is empty.
When Colonel Potter shoots his crushed jeep, his .45 is clearly not loaded. The slide does not kick back when he "fires" it. The gunshot sound effect was added in post production.
Frank is able to steer the tank, so all he would have to do would be to pull back on both sticks and the tank would stop. Also, he thought to use the kill switch, which he could have done when he first lost control.
When Hawkeye asks Radar to get Col. Griswald on the phone to borrow a tank he initiates the call from Col. Potter's desk and then drags it over to him on the floor. There is no wire leading from the phone box to the wall.
Col. Potter fires his sidearm directly into the 'fallen' jeep. As someone with over 20 years in the army, Potter would know better than to fire into such a pile of metal, risking a ricochet into innocent bystanders.
Sgt. Kimble tells Hawkeye that he (Hawkeye) has him (Sgt. Kimble) by the "eustuchian tube," pronouncing it "yu-stoo-shan." It should be "Eustachian tube," pronounced "yu-stay-shan," which is a tube that connects the middle ear cavity to the pharynx (throat). However, Sgt. Kimble, not being college educated, would be mis-pronouncing large words he is unfamiliar with.
When Hawkeye calls Col. Griswold to ask for the tank, he tells Col. Potter that he had treated Griswold for a case of "carnal flu." But when Griswold delivers the tank, Potter asks Griswold if he would like "a belt for the road." Potter should have known that abstaining from alcohol is part of Griswold's treatment for "carnal flu."
