Final answer:
An Army service member can drive on a military installation with a valid driver's license and a military ID. A signed permission slip is not typically required, but registration of the personal vehicle on base may be necessary.
Step-by-step explanation:
On a military installation, service members (SM) typically require several items to operate a vehicle legally. The basic requirement is a valid driver's license, which must be current and applicable to the type of vehicle being driven. In addition, a military ID is often required to prove identity and authorization to be on the installation. A signed permission slip is generally not a standard requirement for driving on a military base. However, service members may need to register their personal vehicle with the base's transportation office or Provost Marshal's office to receive a vehicle pass or decal allowing them to drive and park on the installation.
