The U.S. Army will be putting most of its ceremonial horses up for adoption as part of its overall warfighting realignment, the service announced on Tuesday. The changes will save an estimated $2 million a year,

The Army is giving the affected bases 12 months to shutter the ceremonial cavalry units, and 141 horses will be adopted outside the military.

Meanwhile, army bases in California, Arizona, Kansas, Oklahoma, and Texas will sunset their MWE programs. European colonial settlers relied on horses for centuries, but official US cavalry forces are traceable all the way back to the Revolutionary War.
