1. A military vehicle comprising:
a driveline comprising an engine and an integrated motor generator (IMG);
a front end accessory drive (FEAD) comprising a plurality of accessories and an electric motor-generator; and
processing circuitry configured to operate the military vehicle according to a plurality of modes including an engine mode and an ultrasilent mode;
wherein in the engine mode, the engine drives the FEAD and drives tractive elements of the military vehicle through the IMG for transportation;
wherein in the ultrasilent mode, the engine is shut off, and the IMG drives the tractive elements of the military vehicle for transportation using energy from an energy storage system (ESS); and
wherein when the military vehicle is operated according to the ultrasilent mode, transitioning out of the ultrasilent mode is limited until receiving a user input to transition the military vehicle out of the ultrasilent mode, even if the ESS reaches complete energy depletion.
