What advice would you give someone going into a Military Police occupation?

Honestly, don't be a dick. Too many times I have run across MPs that are extremely full of themselves and just itching to extent their perceived aura of importance and authority. Not saying that MPs don't have importance and I'm certainly not saying they don't have authority. Just don't be a dick about it.

Don’t

You will never know what is right. Being an mp is confusing. But you will always know what is wrong. Don’t ever do the wrong thing.
