January 22, 2077: Power armor is used for the first time for domestic purposes within the United States by U.S. Army units deployed within American cities for crowd and quarantine control duties related to the growing resource shortages and outbreaks of epidemic disease. Units originally serving in China and on the Anchorage Front Line find themselves fighting fellow Americans at home as the disorders grow worse across the course of this year. Food riots increase, and many civilians are killed in fights with the military and police. A growing number of soldiers desert from the American military both in Canada and the United States. These deserters are captured when possible by military policemen and are sent to various military prisons across the United States. Some of these prisoners are later used by American military scientists in illegal human experiments at the Mariposa Military Base in California where the Forced Evolutionary Virus is first tested.

The armor usually carries enough fuel to last for ten thousand years.

So, yeah, not an immediate problem. The guy's a power armored soldier. It's what he does. There's no reason to be so nervous about him "breaking the game", or being better than your character because he has it. If [i]you[/i] want to make a power armored soldier, I'm sure you can.
