Who must maintain a local custody file for all material issued?

The requirement to maintain a local custody file for all material issued falls on both the COMSEC Manager and the Local Element personnel. This shared responsibility ensures that all aspects of communication security (COMSEC) are properly handled and that there is accountability throughout the organization.

The COMSEC Manager typically oversees the security protocols and policies regarding COMSEC material, while Local Element personnel are directly involved in handling and executing tasks related to that material. By requiring both parties to maintain a custody file, it provides a system of checks and balances, promoting thorough oversight and compliance with security regulations. This collaborative approach aids in effectively tracking the movement and status of sensitive materials, thus reinforcing the integrity and security of COMSEC operations.

In contrast, limiting this responsibility to only one group, such as the COMSEC Manager or Local Element personnel independently, would risk gaps in accountability and oversight, potentially compromising the security objectives of the organization. Hence, both must work together to ensure proper record-keeping for all COMSEC material issued.
