Rodney waits until his bunkmates are asleep, then runs off to tell Liceman about their plans. On his way out, he falls off the porch steps into the bushes, and his hat flies off. He gets up, and continues on his way, leaving his hat in the bushes. In the next scene, he has his hat back.
During the scene where the boys are eating and Chooch is about to reveal the recorded conversation between Rodney and Liceman, Rodney gets up to leave because he is disgusted with the fact that they're eating "pig balls." In the next shot it, shows Chooch listening to the them at the next table. In the background, you can clearly see Rodney still sitting at the table.
When the soccer game is being announced, you can see Commandant Causeway is in the stands sitting next to his wife. Causeway reaches over and wraps his arm around Bliss. Then it cuts to a close-up of him, and you can clearly see Bliss is no longer next to him and that seat is empty. His wife also has a gas mask up to her face. Then it cuts back to Keck who is announcing Sisson's performance, and the gas mask is not on Causeway's wife's face, but instead resting on her lap. Then the camera goes to another close-up of Causeway who is asleep on Bliss's shoulder while his wife is itching her nose. But in the immediate next shot, she is setting the gas mask beside her.
During the soccer game when Liceman has the ball, he shoves a kid - with a number "1" on his jersey - onto the ground. In the next shot, Sisson is helping the kid up but instead his jersey now has a "3" on it.
During the soccer game after Hash tells Oliver he has the key, it shows the soccer players on the field. You can see Sisson on the upper-right hand of the screen running amongst the players (you can tell it's him because of his plain black uniform and the way he's running.) In the next shot he's disappeared from the field. In the shot after that, he is on the sidelines talking to another referee: "Did you see that? They're so rough!"
This goof is about the part where Ververgaert informs Liceman about the boys' plan to get the pictures back. While Ververgaert's talking, Liceman says "Will you go ahead?", wanting Rodney to hurry and continue with what what he's saying. Although, when Chooch plays back the conversation on his tape recorder, Liceman says "Will you go on?"
This goof takes place during the scene in the game-room where Oliver, Ike, Rodney, and Hash have devised a plan to trick Chooch into thinking they're not going to try to get the pictures back. You can see the four boys at a pool table with Chooch at another pool table in the background. When the camera cuts to a close-up of Chooch, the balls on his pool table change positions.
At the soccer game (not when the kids are practicing), right after the announcer says "Cadets 1, faculty nothing", when Liceman is running down the field, you can see the shadow of the camera on the grass.
In the soccer game near the end of the movie, the cadets play the faculty and alumni team. At one point, the cadets in the yellow jerseys work hard to clear the ball from deep in their own zone. However, their goalie is actually the faculty/alumni goalie, wearing the black jersey.
