Purpose of AF Form 938, Request and Authorization for Active Duty Training/Active Duty Tour.

Use AF Form 938 to order members of the Air Force Reserve to special, annual, school, military personnel appropriation (MPA) tours, and special tours of active duty without pay for the purpose of permissive temporary duty (TDY). Do not use AF Form 938 to order members to extended active duty; to involuntarily recall a member to active duty for the purpose of disciplinary action, or to continue a member beyond the time limits of an existing order to satisfy disciplinary purposes under the Uniform Code of Military Justice (UCMJ); or to order an individual to active duty for the purpose of medical treatment or hospitalization.

Identifying AF Form 938. Publish AF Forms 938 generated by the Air Force Reserve Orders Writing System-Reserves (AROWS-R) for unit-assigned reservist and IMAs with a prefix of "D" to identify the series of orders (for example, D-1, D-2). In the event orders are required to be prepared manually, use a two-letter prefix to differentiate between those orders prepared in AROWS and those prepared manually..
