Can I still get a job as a cop with an Other Than Honorable discharge?

I am getting court martialed for violating a few articles of the UCMJ. It is a BCD Special-Court Martial. I am a Staff Sergeant in the U.S. Army and just don't want this to hurt me significantly. I messed up as an instructor of trainees and just wanna get out and be able to be a cop or work as a fireman or EMT.
