The United States military has utilized horses since the nation’s inception, but its equine era is finally ending. 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. A separate United States Cavalry was not formed until 1861, but it remained a distinct Army branch until World War II. In 2001, Army Special Forces relied on horses provided by Northern Alliance partners during the early days of the Afghanistan invasion.
