Range OIC and Range Safety Officer Appointment Memorandum (OIC-RSO)
The Range OIC and Range Safety Officer appointment memorandum is an AR 25-50 compliant memorandum used to formally designate a Soldier or DA Civilian to serve as the unit's Range OIC and Range Safety Officer. It documents the appointee, references AR 385-63 (Range Safety), and is signed by the commander.

When is the OIC-RSO memo needed?
Most Army units appoint a Range OIC and Range Safety Officer (OIC-RSO) when a new commander takes charge, when the previous appointee PCSes, ETSes, or is reassigned, or when the unit's mission set changes in a way that requires renewed appointment. The memo is also required for unit inspections — including CIP, CCIR, and command climate reviews — where the AR 385-63 program is evaluated.
The appointment memorandum is the foundational document that establishes the appointee's authority under AR 385-63. Without a current, signed appointment memo on file, the unit's Range OIC and Range Safety Officer program is non-compliant — even if the appointee has all required training certificates. Inspectors will look for: a signed memo with current date, a grade that meets OIC — Officer. RSO — NCO or Officer per DA Pam 385-63, and training/certification documents matching the appointee on the memo.
