Anything with an SAE #1 flywheel that put out 445HP or less at 1400ft-lbs or less peak torque. Really common in the private sector too - my Bus has one.
One thing to watch for - the lock-up clutch on the military version is aggressive, this is why they had to put anti-lock brakes in the M939 series trucks. Guys were stomping on the brakes and the lock-up clutch wouldn't release, killing the engine and thus the power steering.
[Edit:] Should note, the lock-up clutch is accessible via a hydraulic port - you can add a solenoid valve and make the lock-up clutch controllable. I have a full factory service manual if you have any questions [/Edit]
