First Step

The first step is to become a Marine.

The prerequisites for CSOs and SOOs are:

  • Have a minimum GT score of 105 for enlisted, or GTC of 110 for officers.
  • Have a minimum PFT of 235. 
  • Be able to pass the MARSOC swim assessment.
  • Meet the MARSOC medical screening criteria.
  • Be eligible to obtain and maintain a secret clearance.
  • Be willing and able, upon selection, to make a lateral move to the critical skills operator MOS.
I joined MARSOC for the same reason I became a Marine—intense, determined people who aren’t afraid to win.
