My 2 cents...
Since you have an interest in a Federal LEO gig and also something highspeed in the military. Think about getting off Active Duty and entering the Reserves/NG as a 35M or 35L while checking off the college box. A degree in Intelligence Studies, Homeland Security,etc... would be good. If I were 21 again I would have gotten my degree in Intelligence Studies. Anyway... those are not SF long tabbed wearing jobs but can be very interesting and seem to be inline with your long term goals.
As a 35M (HUMINT Collector) you would get some very good training and schools if you go to the right unit and are an NCO. Some of the schools that would be available to you are in high demand by not only Federal LEAs but DoD Intelligence agencies that you might want to consider. I am not a 35M but I have several close friends who are and they did went on to dive and jump school and they have some very interesting work.
As a 35L (Counterintelligence Special Agent) you would be an accredited Federal Agent and among your responsibilities would be to investigate Treason, Sabotage, Sedition, Espionage and other National Security Crimes within CI jurisdiction. The experience would be invaluable for someone looking at being a FLEO. There are high speed opportunities available in and out of the DoD. There are 35L at the SF groups and there are 35L who work around the country assigned to the FBI Joint Terrorism Task Force.
A CI/HUMINT background makes you attractive to the Feds. I have had a few offers. Customs, ICE,etc...
Just something to chew on. Good luck!
