After completing both Range Safety Courses, establishing your Read-Only RFMSS Account, and submitting your certificates; the last step is to be appointed in writing by your unit Commander. This Appointment Letter gives Range Management Branch the confidence that the OIC is knowledgeable and the RSO is qualified in the weapon systems and ammunition they will be responsible for while training in the Quantico RTA.

The template provided is in Standard Naval Letter Format but can be copied into any other DOW agency format for official correspondence. This template is intentionally generic to allow additions and deletions of personnel in RFMSS rather than a new letter required every time personnel turnover occurs. If your Unit Commander prefers rosters or individual by-name letters, that is their prerogative and a more than acceptable alternative. Check with the IRSO to see if your unit already a current letter on file.
