Urinating Brute
From Halopedia, the Halo wiki
300px|right On the level "The Ark", when you reach the room with sleeping Grunts, if you continue farther in the level there is a Brute urinating in the corner. Originally, he has his hands in front of him, but after a short time he will move his hands behind his head and then shake the excess urine off himself. After a while he will move into the main hallway and get into position waiting for intruders.
Trivia
- The Brute is not always the same rank, however it's almost always a Captain. Usually if the Brute is a higher rank it will notice you a lot faster.
- If you watch the Brute on Theater mode, he seems to be "zipping" or "pulling" up his pants before turning around.
