I am about to go to Warrant Officer Candidate School. What advice/tips do you wish someone had told you before you got there?

Learn to manage egos. Your own, and your fellow candidates. Just about everyone there was a stellar soldier where they came from.

Also, get your us army and nametapes sewn on.

Know when to lead. More importantly, know when to follow.

Just stay humble, you will be working with alot of people with different personalities. Work together and you will have fun.
