Corrected entry: During the scene when the trainees are waking up prior to their graduation, one trainee says "graduation is at four o'clock, what time is it?" The other trainee says "its 3 o'clock, we still have an hour of sleep." That would be correct. They act as if they are an hour behind, missing graduation, when in reality they would have time to get their act together and show up to graduation on time.
Corrected entry: After hustling Bill Murray and Harold Ramis onto the bus to basic training, the brunette MP turns to the blond MP and you can see her enlisted rank on her sleeve. She's wearing a Specialist 5 rank displaying an inverted green chevron shaped patch with a gold eagle in the middle and a curved, gold stripe over the top of the patch. Later on, at the graduation ceremony when the 2 MP's are sitting together in the bleachers, the same MP is now only a Specialist 4. The patch is the same, but the gold stripe is gone. Was she demoted between the time of the bus station scene and the time Bill Murray graduated from basic training?
Corrected entry: Realistically speaking, if 2 Army Privates had actually stolen a top-secret vehicle and wreaked the havoc that they did, they'd be immediately discharged from the Army and doing hard time in jail - definitely NOT coming home to a hero's welcome like they did.
Corrected entry: During John and Sgt Hulka's "heart to heart" talk in the latrine, Hulka says that he's been in the Army 28 years. Hulka's rank was an E7 (Sergeant First Class). It's not possible to be in the Army that long as only an E7, you'd have to be at least an E9 (Sergeant Major) - in which case you wouldn't be a drill sergeant since Sergeant Majors aren't drill sergeants.
Corrected entry: When the soldiers are held captive and Bill Murray tries to blow down the door, there is an unknown soldier within the cell (small person), he is on the right of all the rest. When the door is broken down by John Candy, you can barely see the same person in the back of the rest of the soldiers jumping up and down wildly.
Corrected entry: Throughout the whole movie, Captain Stillman has lieutenant's bars on his hat and/or shoulders. He should have captain's ensignia, which is one bar, not two.
Corrected entry: Throughout the movie ALL the characters salute completely improperly. As a comedy this is not unexpected, however, in this movie the high ranking officers are depicted correctly and accurately within military decorum, yet they also salute totally inappropriately. Specifically, at the end of the salute your arm is dropped straight down to your side at the attention position immediately, which they fail to do. This is a mistake regardless of this being a comedy, drama or any other genre.
