Plan for the unexpected with your frickin' tank
Since movies shoot in non-sequential order, action involving tanks is often all over the place. In Wonder Woman, for example, the Ehrhardt had to be shot flipped on its side, post-crash, first. King, drawing on past experiences, predicted the backward flow of production in the early stages of his build and called for extra safety measures to protect the armored car -- which he reproduced using a stripped-back flatbed truck that had been adjusted from the chassis up. King and his team built side feet so when it came time for a crane to lift and turn the car over, it could sit safely, covered in dust, looking like it had just been smashed and spun.
Afterward, King and his team got the Ehrhardt upright, unbolted the side legs, and cleaned it so it would look brand new for its pre-catapult scene. "You need to see the unforeseeable," when working with tanks, King says. "You need to cover yourself in Teflon."
Don't actually kill anyone with the frickin' tank
Safety is key: You'll need your people on the inside, effectively blind, communicating via radio with the first assistant director to slow down, speed up, turn left, and, when applicable, wreck shit. They'll need helmets ("Everything's metal, everything's hard," King says, "so you've only got to turn your head in the wrong direction and you're braining yourself on a corner of steel"). And you'll need banksmen -- personnel and safety measures vary depending on the scene's requirements, but King says you'll want a front banksman and a rear banksman at minimum -- to ensure production flows sans human pancakes.
