Definition

Military jargon for disembarking from a bus or transport vehicle, because apparently 'getting off the bus' wasn't tactical enough for the armed forces. This term reflects the military's love affair with creating specialized vocabulary for mundane activities. Troops debus when arriving at training sites, deployment zones, or anywhere else a regular civilian would simply 'step off the bus.'

Example Usage

The platoon will debus at 0600 hours and immediately establish a defensive perimeter, as if they weren't just on a chartered coach.
