If you are not a military member of the PRARNG (i.e. Airman, civilian, active-duty Soldier, prior service, guard member from another state, reservist, IRR, State Guard, etc.), you must contact the Recruiting and Retention (R&R) Office at (787) 289-1400 extension 2015 or 2008 and request the PRARNG Military Basic Requirements (MBR) Certification. If you are a male applicant who was born after 12/31/1959 and are required to register under the Military Selective Service Act, the Defense Authorization Act of 1986 requires that you be registered, or you are not eligible for appointment in this agency ( https://www.sss.gov/RegVer/wfRegistration.aspx ).
