In January, the Army began officially testing the Chevy Colorado ZH2, the first ground-mobility combat vehicle that, if fielded, would be powered by a revolutionary new hydrogen fuel cell. The result of a $4 million collaboration between GM and the U.S. Army Tank Automotive Research, Development, and Engineering Center (TARDEC), a functional hydrogen fuel cell would mean a greatly diminished heat signature and near-silent electric power system, making the ZH2 not just a more efficient pickup for military operations, but a strategically valuable asset downrange. Less noise means less exposure, which means less risk of showing up on enemy scopes.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
