Betushka tank treads and power plant with the chassis only half stripped. Too far into the third six pack, the Corvids bolted a van on top and called it a day. "Party Vans" come in various irregular variations but they're all about the fastest, laziest way to take a disabled Loyalist light tank back into service with a Corvid flourish for the ridiculous. I heard one time they didn't even bother cleaning out all the guts of a BT driver before welding the van on top. Couldn't hose the smell out of the thing. Driver and gunner were just drunk with an extra cooler in the front any time they had to go out on a mission. So exactly like every other Party Van crew, come to think of it.
