A new report by the Government Accountability Office warns the US military may * run out of national guard and reserve troops* for the war on terrorism because of existing limits on involuntary mobilizations. Since the September 11 attacks more than 335,000 guard and reserves have been involuntarily mobilized for active duty. The report also notes that the army national guard has failed to meet recruiting goals in 14 of 20 months between October 2002 and May 2004.
