Hooah

Hooah is a battle cry used by members of the United States Army. 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 U.S. Army and gained a more general meaning of "anything and everything except 'no'.

It is comparable to Oorah which the United States Marine Corps uses.
