Hooah

Hooah is the Army's verbal Swiss Army knife. It means 'I hear you,' 'yes,' 'understood,' 'that's awesome,' and 'let's go' depending on context and delivery. Origin is debated; one common theory: HUA = Heard, Understood, Acknowledged. You will hear it hundreds of times per day at BCT. Using it correctly (with conviction) is an early social skill at basic.
