Let’s see...
The Marines have “Oorah...”
The Army has “Hooah... (at least it started getting popular in the 80’s, before that I only heard it near the Ranger Battalions).
Apparently the Air Force picked up on it too (I thought they said “Zoom!”) :)
The Navy and Coast Guard has used “Ooyah” or “Booyah” depending on who you ask.
Space Force? I guess that they have to start new traditions. They will probably say “Qu’vatlh!”
Live long and prosper, y’all!
It’s absolutely ‘live long and prosper’.
No question!
A officer once told me Hooah is an acronym "HUA".
It's called out in unison as an affirmative, when being addressed by a superior officer.
"HUA" meaning; Heard, Understood, Acknowledged.
