Amusingly, we did this at the Army Reconnaissance Course. I was in one of the last courses still based out of Fort Knox before the Armor School relocated to Benning and our capstone field event was basically a survivor pool where we split into teams starting at the perimeter of the installation and gradually move inward surveilling all of the facilities while the school staff tries to find us. Whoever is the last to get caught wins. The MPs and US Mint Police were, of course, told we were doing this so they wouldn't shoot us. I do recall an incident from a bit more than a decade back, I think at Fort Bragg, where a soldier going through the special forces Q Course was shot by a police officer.
