A driver without base access credentials is a bus that cannot complete the pickup.
Base access for military installations typically requires advance credentialing for both the driver and the vehicle, submitted days or weeks ahead depending on the installation's security posture. A carrier experienced with military and government moves manages this proactively rather than discovering the requirement the day before pickup.
Government agency transportation, meanwhile, often runs through a formal procurement or contracting process, which means the carrier needs to be able to work within purchase orders, government rate structures, and documentation requirements that differ from a standard commercial invoice.
