I Swear I Just Saw Soldiers Marching Down the Street

What are you supposed to do when you're hanging out on your balcony and all of a sudden twenty-five soldiers in camouflage come around the corner in marching formation?

Strangely, this is something I've always wanted to see now that I am situated at a perfect height above the street. Maybe next time they could drive a tank through as well. You know, just to make it authentic.
