FILE - This undated file photo provided by the U.S. Army shows Brig. Gen. Jeffrey A. Sinclair. The number of U.S. soldiers forced out of the Army because of bad conduct or crimes has soared in the last several years, as the military comes out of a decade of war that put a greater focus on battle competence than character. Data obtained by The Associated Press shows that the number of officers who left the Army due to misconduct tripled in the last three years. And the number of enlisted soldiers forced out for drug, alcohol, crimes and other misconduct shot up from about 5,600 in 2007 as the Iraq war peaked, to more than 11,000 last year.
