Aside from all of the suggestions, so far... if you're really interested in combining a law enforcement career with some sort of military experience, you might consider the various services' criminal investigative servies.gordonramsay wrote: ... I'd like to join some sort of Federal Law Enforcement branch... I just want to serve my country like my father did during Vietnam(USAF 380th Bombardment Wing). I considered Navy or Airforce OCS but that would be way to drastic of a change and you don't really get that many opportunities compared to Academy graduates.
For the Air Force, it's OSI - Office of Special Investigations http://www.osi.andrews.af.mil/. They have both military and civilian investigators with assignments all around the world (not only at Air Force bases) and do hire non-experienced civilians as OSI trainees: http://www.osi.andrews.af.mil/questions ... /index.asp
For the Navy and Marines, it's NCIS - Naval Criminal Investigative Services http://www.ncis.navy.mil/Pages/publicdefault.aspx
For the Army, it's CID - Criminal Investigative Command http://www.cid.army.mil/
and for the Coast Guard, it's the Investigative Service (CGIS) http://www.uscg.mil/hq/cg2/cgis/
All of the services are different, of course - I've known a few Army CID and AFOSI folks, and all of them seemed like they were happy they had taken the chance to move into the military's law enforcement/investigative branches.
