I've never paid close enough attention to notice if the troops were dancing.........lol.
I did encounter a lone trooper the other night, standing way WAY out from our base, all alone. For some reason he wasn't able to keep up with his comrades on their trek to their doom.
Looked like he was lost, or taking a break, or just tired from being dropped so far away from his objective. On further thought, it's probably just that he was a smoker......lol.
Regardless, I put him out of his misery.................
