Despite this roster of troubles, many Army officers remain upbeat. Brigadier General Sean Byrne, the Army's director of military-personnel policy, says that while "the going will be tough" in the months to come, the Army has the tools to keep its force properly manned. "The war on terror strikes home with everybody," he says, "and it motivates them to come on board and stay with us." Rumsfeld and Byrne believe that there is enough goodwill among young Americans out there to fill most of the ranks--and enough money to lure in the rest. Mills, the wounded Army reservist, is the kind of American they're counting on. "My buddies are expecting to be deployed again," he says. "And if I weren't injured and they called me to go again, I'd absolutely go." ???
