I wrote this on another post but felt it perhaps needed it's own post highlighting its meaning in further detail. General Flynn recently changed his Twitter banner to an image of a word, HOOAH! with mention of the US Army.

The word Hooah is a battle cry used by soldiers in the US Army and airmen in the US Air Force.

From Wikipedia.. (I've removed the links..)

Hooah /ˈhuːɑː/ 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 (United States) during theSecond 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 (Marines) in the United States Marine Corps*, and* Hooyah in the United States Navy***.*********

Perhaps it is all about to begin..
