COMSEC Custodian Appointment Memorandum (COMSEC_CUSTODIAN)
The COMSEC Custodian appointment memorandum is an AR 25-50 compliant memorandum used to formally designate a Soldier or DA Civilian to serve as the unit's COMSEC Custodian. It documents the appointee, references AR 380-40 (Safeguarding and Controlling Communications Security (COMSEC) Material), and is signed by the commander.

When is the COMSEC_CUSTODIAN memo needed?
Most Army units appoint a COMSEC Custodian (COMSEC_CUSTODIAN) 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 380-40 program is evaluated.
The appointment memorandum is the foundational document that establishes the appointee's authority under AR 380-40. Without a current, signed appointment memo on file, the unit's COMSEC Custodian 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 E-5 (SGT) or GS-4 minimum, and training/certification documents matching the appointee on the memo.
On EvalMe, the COMSEC_CUSTODIAN memo is one of 39 AR 25-50 templates that auto-cites the correct regulation, uses the proper format, and integrates with your unit's address book and signature blocks.
