War survivors wrestle with military bureaucracy, personal demons
"Even among the gazebos and tranquility of the Walter Reed campus in upper Northwest Washington, manhole covers are sidestepped for fear of bombs and rooftops are scanned for snipers"(At Mologne House a struggle to recover, Washingtom Post).
