There are also some inherent performance advantages to embracing hydrogen, including high torque (since it's powering an electric motor) and high fuel efficiency. You could even reuse the cell's water output. Chevy also tells TechCrunch that having exportable power could make it easy to fix vehicles -- you could swap fuel cells in the field.

The US Army plans to test the ZH2 in "extreme field conditions" during 2017. There's no guarantee that the truck will enter service, and we could see a few obstacles to it: it's still expensive to produce hydrogen, and it's not as readily available as fossil fuels. A stranded unit likely couldn't scrounge up fuel without calling in support. It's hard to deny the advantages, however, and it's easy to see fuel cell trucks finding at least some use in combat.
