At the end of the episode, Hogan pours himself a glass of wine. In the long shot before and after he drinks, he has a traditional wine glass, but in the close-up he is drinking from a cocktail (cone-shaped) glass.
Larry Hovis returns as Sgt Carter and in the pilot, he is Lt. Carter. who escapes Stalag 13.
It was stated in this episode that Klink has been a colonel for 20 years. In future episodes, he is mentioned as being 49 and 50 years old. This means that he became a colonel at 30 years of age. Almost unheard of in any army during this time frame.
When Newkirk (as the Gestapo officer) pulls out his orders and hands them off, it is a sheet of paper folded in thirds with another fold near one end of the folded paper. When Schultz hands them to Klink, the orders are in an envelope. When Klink takes the orders out of the envelope, they are on a sheet of paper folded in thirds, with another fold near one end of the folded paper. In other words, when Newkirk hands his orders off, they are not in an envelope, but when Schultz hands them to Klink, they are in an envelope.
The "Tiger tank" is actually a U.S M7 Priest Mobile gun.
The tank is incorrectly marked with an incomplete Imperial War Banner (Reichskriegsflagge, lacking an Iron Cross in the top left corner). It should be marked with a stylized Iron Cross.
In various episodes Sgt. Schultz is carrying a 30/40 Krag issued to American troops in the late 1800's. He should have had a k98 Mauser from the period or a GEW leftover from WWI at the very least. The Krag is distinct in the cartridge magazine being on the bolt side of the weapon.
Newkirk at one point offers to share his 'cubicle' with Tiger. This is an open barracks; there is no cubicle for anybody. Newkirk has to be referring to his bunk area.
When Newkirk sends the tank out of the Recreation Hall, no one appears to be driving it. However, it does a very nice job of steering around the barracks before exiting the camp.
The Tiger tanks are new and secret, yet Newkirk is able to drive it like an expert, perfectly driving it into the barracks, through an opening barely big enough to allow it in - which also means they know the exact dimensions of the tank.
After the Heroes hide the tank the Germans claim that they cannot find it, yet when the tank is moving across the ground, it leaves highly visible, deep tracks in the soil. All the Germans would have to do is follow the tracks.
Knowing that the tank is a tracked vehicle, Hogan would have had someone assigned the duty of erasing the track prints in the ground during the confusion of LeBeau's escape to hide where the tank actually went.
