OK, first off get 3-5+ years of SpecOPs experience, meaning you go through Green Beret or Airborne or SEAL training then do 1-2 tours in notso-hotso places around the Globe.
Document your achievements. Attain a rank of E-5 or better, establish some MOS that involve VIP security, close combat, communications, logistics, transport, etc.
Learn to speak Farsi or Aramaic or Arabic. Fluently.
Then go for it.
Granted you CAN get a job, at a lesser rate of pay, with lesser qualifications.
Know that 700+ "contractors" have died in the Sandbox since the fun & games began and perhaps 7000+ have been wounded/injured.
