Details of how the Army will cut an estimated 40,000 active duty troops and 17,000 civilians across the U.S. will be unveiled at 11 a.m. Thursday, according to Cynthia O. Smith, deputy division chief with Army Media Relations. El Paso County, home to Fort Carson, has long anticipated these cuts after a worst-case scenario laid out in a June 2014 document showed the base could lose two-thirds of its troops or about 16,000 soldiers by 2020.
