The units from Utah that served in this fashion were batteries A and B of the Utah Light Artillery; Troop A, Utah Cavalry (regular cavalry); and Troop I of Torrey's Roughriders (a special troop of mounted riflemen). Most of the enlistment into the artillery batteries A and B, Utah Volunteers, came from the National Guard of Utah A and B batteries; and Troop A, Utah Cavalry, came mostly from the National Guard Cavalry Troop C. Torrey's Regiment was designated as special cavalry for the state and was recruited from throughout the state. Company K of Engineers, 2nd Engineer Regiment, U.S. Volunteers, was recruited from Salt Lake City, and another two hundred men from Utah were recruited into the 4th U.S. Cavalry, the 14th U.S. Infantry, and the 11th U.S. Cavalry. In addition, two Afro-American regiments--the 24th Infantry, Regular Army, stationed at Fort Douglas, and the 9th Cavalry, Regular Army, stationed at Fort Duchesne in eastern Utah--left the state to fight in the Cuban and Philippines campaigns.
