What are some of the best schools for soldiers that help land law enforcement and fire jobs after retirement?

Army schools only I have a degree

Honestly, most departments don't care what you major in and a few will even take people who only have a high school diploma. If you want to join a sheriff's office and plan to stay there for a while, then look at majoring in corrections. An accounting degree could help you if you want to eventually become a fraud investigator. A degree in IT could help your career too. Law enforcement needs people who are well rounded and able to adapt into all aspects of law enforcement. Good luck.
