The United States Cavalry, or U.S. Cavalry, was the designation of the mounted force of the United States Army from the late 18th to the early 20th century. The Cavalry branch was absorbed into the Armor branch in 1950, but the term "Cavalry" remains in use in the U.S. Army for certain armor and aviation units historically derived from cavalry units.
Originally designated as United States Dragoons, the forces were patterned after cavalry units employed during the Revolutionary War. The traditions of the U.S. Cavalry originated with the horse-mounted force which played an important role in extending United States governance into the Western United States after the American Civil War.
