A military vehicle includes an engine, an energy storage system, an accessory drive coupled to the engine and including an air compressor and a first motor, a second motor coupled to an axle, and a clutch positioned between the engine and the second motor. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. In an engine mode, (i) the clutch does not receive the air supply such that the engine is coupled to the second motor and (ii) the engine drives (a) the accessory drive and (b) the axle through the second motor. In the electric mode, (i) the first motor drives the air compressor to compress air to facilitate supplying the air supply to the clutch to disengage the clutch and decouple the engine from the second motor and (ii) the second motor drives the axle.
