What does "Hoaah" mean?
If you’ve spent any time around an Army base you’ve heard this one. It’s probably the most common exclamation in the military. So what does it mean? A good question – many think it comes from the phonetic spelling of the acronym “HUA,” which stands for “Heard, Understood, and Acknowledged.” In other words, it’s a way of saying “Yes, Sir!” But a hearty “Hooah!” just sounds tougher, doesn’t it?
