Which of the following is NOT a part of local custody responsibilities?

Training local personnel is a critical component of maintaining effective COMSEC practices; however, it is typically not considered a direct part of local custody responsibilities. Local custody responsibilities primarily focus on the physical protection and proper documentation of classified materials. This includes safeguarding the materials to prevent unauthorized access, documenting how materials are handled and transferred, and ensuring the appropriate disposal of materials that are no longer needed or are obsolete.

The role of training personnel, while essential for ensuring that everyone understands appropriate security protocols and procedures, is often seen as a separate requirement. It usually falls under the broader framework of organizational policies or specific training programs rather than the localized custody tasks that deal directly with the physical security of materials. Therefore, while training is vital, it does not directly align with the responsibilities associated with the custodial management of COMSEC materials.
