Which device is used to recommend or request an award?

The DA Form 638 is specifically designed for recommending and requesting awards for military personnel. This form provides a structured format for detailing the accomplishments and achievements of the service member being considered for an award, facilitating the evaluation process by leadership. It includes sections for the proposer to clearly outline the criteria met for the specific award, the service member's performance, and any relevant supporting documentation.

In contrast, the other forms serve different purposes: DA Form 4856 is used for developmental counseling, DA Form 2166-9 is a NCO evaluation report to assess performance and potential, and DA Form 1059 is utilized for academic evaluations in military schools. Each of these forms has a distinct function that does not pertain to the award recommendation process, thereby reinforcing the unique role of DA Form 638 in this context.
