A day in the life of the Marine Corps' Mounted Color Guard Marine Corps Sgt. Fernando Blanca, a stableman with the Corps' last remaining mounted color guard, mucks out a horse stall at the stables on the Yermo Annex of Marine Corps Logistics Base Barstow, Calif., Aug. 8, 2017. Cleaning stalls, grooming the horses and maintaining the facilities is all in a day's work for the stablemen.
