The U.S. Army said Tuesday it will shut down most of its horse-mounted ceremonial units within the next 12 months and find new homes for roughly 141 horses, marking a decisive break with a tradition that stretches back to the service’s cavalry roots. Units at Fort Cavazos in Texas, Fort Carson in Colorado, Fort Sill in Oklahoma, Fort Irwin in California, Fort Riley in Kansas and Fort Huachuca in Arizona will be disbanded. The Army will keep only the Old Guard caisson platoons that perform funeral honors at Arlington National Cemetery and Joint Base San Antonio. Spokesperson Steve Warren said the decision is part of a broader realignment toward war-fighting readiness and is expected to save about $2 million a year. “The horses are part of the Army family; we’re going to treat them with compassion,” he added, noting that the animals will be adopted or donated but not sold.
