Stupidity: When Capt. Stillman orders the soldier to launch the live mortar shell without verifying the coordinates, it lands way off course where Sgt. Hulka and his platoon are training, almost killing them. This would have been a court-martial offense for Capt. Stillman, not to mention the national media coverage it would have generated. But Capt. Stillman retains his position without any consequences.

Suggested correction: Realistically, of course. But this is a comedy. Stupid things are supposed to happen to add to the humour. I mean later in the movie, they steal a top secret military vehicle and use it to cross into Eastern Europe. They should all go to jail for life. But of course, that would be a really bad ending for a comedy.
