Continuity mistake: As Schultz is going to get checked out, Hogan and the boys stop him, and Hogan feels Schultz's neck. Schultz's arms are by his sides, then after the angle change, they're by his hips. Also, there's two men walking behind the group that weren't there a second before.
Continuity mistake: Newkirk and Le Beau are getting the girl into the tunnel via the doghouse, while Hogan has Schultz distracted. Look over Schultz's left shoulder. The doghouse is in its correct position, as you can see the roof. When Schultz turns around, Le Beau and the girl are pulling the doghouse down, where it was down about one second earlier.
Continuity mistake: When Klink does a walk through in the barracks, he turns to face Hogan in front of Schultz. As he does, the end of his riding crop pushes against Schultz's lower chest and sticks. When the camera cuts the crop is free and well clear of Schultz.
