HORSE is also used in the military language, to express the cavalry; or the body of soldiers who serve on horseback.
The horse includes horse guards, horse grenadiers, and troopers. Dragoons are also frequently comprehended under this name, though they fight on foot: of these there are now 18 regiments; besides three regiments of dragoon-guards raised in 1685. See GRANADIER, DRAGOONS, and GUARDS.
