A military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.
