Notes & Sources

  • COMDTINST M5300.3A (Officer Specialty Management System Manual, 3 Jun 2020) establishes the Coast Guard’s Officer Specialty Code system; by its Table 4-1 nomenclature, CG-OAR17 is a Subspecialty code (OAR = the specialty’s abbreviated name; “10” marks the Specialty and “11” and higher mark Subspecialties within it).
  • The authoritative list of approved Specialties/Subspecialties and each code’s Officer Specialty Requirement (OSR) is maintained by PSC-OPM-3 on the CG Portal, which is not public; no code-exact official definition of duties was retrievable.
  • The description shown on this page is Coast Guard recruiting-site category prose aligned by specialty (gocoastguard.com officer categories), not the code’s official OSR; treat it as a general indication of the specialty’s field, not proof of any individual holder’s duties, qualifications, or training.
