The wildest thing I've done to date is run across an open field while a Kiowa Warrior helo fired rockets into a truck carrying ammo, while the truck was cooking off. Thank god the Ba'ath party spent all that aid money to build strong head quarters buildings - there were .50cal size bullets bouncing off it.
Maybe blowing up a bunch of anti-aircraft rounds rivals that - some of them went up and came down near us, exploding on impact. That was more scary than wild though.
