<p>BOSTON – Charla Nash never served in the military. She was horribly disfigured, not in combat, but in a 2009 attack by a rampaging chimpanzee. The Pentagon, though, is watching her recovery closely.</p>
<p>The U.S. military paid for Nash's full face transplant in 2011 and is underwriting her follow-up treatment at a combined cost estimated in the hundreds of thousands of dollars, in the hope that some of the things it learns can help young, seriously disfigured soldiers returning from war.</p>
