WTF, you've never seen athletes punch the air when they are victorious?
Even the mild mannered, like chess players and pro wrestlers celebrate a victory.
But say you're right, and it's solidarity. Is it unusual for a military unit to express solidarity, be it basic training, a battle, or West Point? They certainly have something to celebrate after four years of pressure.
Why would these future military leaders say anything, nobody is asking them anything yet. Right now they are being tried by press in absentia.

But that doesn't explain why the leadership of this august institution requires black women to wear confederate uniforms.
