What document must be completed and signed by two personnel when physically transferring COMSEC?

• A. TRI SF-153
• B. COMSEC Transfer Form
• C. COI Transfer Report
• D. Receipt of Transfer Form

Answer: (A)

The document that must be completed and signed by two personnel when physically transferring COMSEC is the TRI SF-153. This form is specifically designed for the transfer of COMSEC material and ensures that there is a formal, documented process in place to maintain accountability and security during the transfer. It requires signatures from both the transferring and receiving personnel, thereby providing a clear record of the transaction, which is essential for tracking and auditing purposes.

This procedure is critical in maintaining the integrity of COMSEC materials, as it helps to prevent unauthorized access or loss of sensitive information. The TRI SF-153 is widely recognized and standardized across various organizations dealing with communications security, making it the appropriate choice for this purpose. Other documents mentioned, while they may relate to different types of transfers or reports, do not fulfill the specific requirements of COMSEC material transfer that the TRI SF-153 addresses.
