The military will phase out its "stop-loss" program, the contentious practice of holding troops beyond the end of their enlistments, for all but extraordinary situations, Defense Secretary Robert Gates announced Wednesday. Instead, the military will use incentives programs to encourage personnel to extend their service. Starting this month, the department will provide "special compensation of $500 per month" to troops whose tour has been extended, Gates said. "This special compensation will be applied retroactively to October 1, 2008, the date when Congress first made it available."
