out forms and records have several uses. They are a permanent record of
services, repairs, and modifications made on the vehicle. They are reports to
organizational maintenance and to your Commander. They are a checklist to
know what was wrong with the vehicle after its last use, and whether those
faults have been fixed. For the information needed on forms and records, refer
to DA PAM 738-750.
