Which form is used for appointment and termination records of authorized signatures?

The correct form used for appointment and termination records of authorized signatures is the DD Form 577. This form specifically serves to document the appointment and termination of individuals authorized to perform certain actions, such as signing documents on behalf of a commanding officer. It is essential for maintaining accurate records of who is authorized to act in a capacity where their signature is required, ensuring accountability and proper delegation of authority within military operations.

For instance, DD Form 553 is used for reporting lost or stolen military identification cards, while DD Form 1351-2 is utilized for travel vouchers, and DD Form 1610 pertains to temporary duty (TDY) travel orders. Each of these forms is tailored to specific administrative functions, highlighting the role of the DD Form 577 in tracking authorized signatures.
