I doubt that. That would defeat the whole purpose. The US DoD has also been pushing into "green" technologies so that remote troops and outposts don't require lengthy and vulnerable supply trains. For example, using solar panels to power lights, radio equipment, battery chargers and other electronics so that fuel for generators don't have to continually be sent out to them.

There are already civilian products out there that condense water from air. Never tried them, but obviously, the amount of water generated will depend highly on the moisture content of the air. They also sell them with quite small solar arrays that reportedly power them just fine, for the ultimate off-grid water source without having to be near a water source.
