What must be available at all times while operating an Army military vehicle?

When operating an Army military vehicle, it is essential to have the DA Form 5984, also known as the Operator's Permit, or an Optional Form 346 readily available. This form is critical as it signifies that the operator is authorized and trained to drive that specific type of military vehicle. The presence of this documentation ensures compliance with Army regulations, which mandate that personnel must be properly licensed for the vehicle type they are operating. This requirement is in place to enhance safety and operational efficiency within military operations.

Other documentation, like a civilian driver's license, insurance documentation, or vehicle registration, while important in non-military contexts, is not applicable in the same way for Army vehicles. The military has its own standards and processes for licensing and documentation, making the DA Form 5984 or Optional Form 346 the key requirement for legal operation of military vehicles.
