When Col. Potter shoots his crushed jeep to "put it down," it's not only a reference to the character's history as a calvaryman, but a reference to the famous WWII Bill Maudlin cartoon depicting a master sergeant with the 5th Calv. shooting his jeep in a similar fashion after it "broke its leg" (i.e. broke an axle).
When Frank is driving the tank towards the Swamp, everything in the Swamp is gone {empty} except the table and chairs that Hawkeye, BJ etc.... are playing poker on.
Bruce Kirby appears as Sgt Kimball. His son Bruno Kirby appeared in the pilot episode as Pvt Lorenzo Boone.
The Jeep that got run over by the tank was junk or scrap before it got flattened. The tires were worn all the way down with no tread left and there was no engine in it
During this episode a tent signed Barber is visible. It's highly unlikely the 4077th would have one of its few tents dedicated to a barber.
Further, throughout the series there's been no mention of a barber nor any scenes in a barber tent.
