Hooah // is a battle cry used by soldiers in the U.S. Army and airmen in the U.S. Air Force. Originally spelled "Hough", the battle cry was first used by members of the 2nd Cavalry Regiment during the Second Seminole War in 1841, after Seminole chief Coacoochee toasted officers of the regiment with a loud "Hough!", apparently a corruption of "How d'ye do!" Since WWII, the word has been widely used throughout the US Army and gained a more general meaning of "anything and everything except 'no'". It is comparable to Oorah in the United States Marine Corps, and Hooyah in the United States Navy and the United States Coast Guard.
