The O.C.O. has expired, but I'll still keep this creation. Let's just say it's a themeless tank.
A small tank used to tranport units and, while it's at it, wreak some havoc with a turbo laser gun.
About this creation
The tank holds up to two units.
Side view. The O.C.O. often uses raised caterpillars.
The driver. He controls the tank and fires the turbo laser gun.
The gun. The rotor rotates rapidly, so the short lasers fired by it are "spread" into a "bullet hell".
The engine. The soldiers are also covering it with the shields.
The minifigs. A driver and two regular units (boy, and I thought those fireman torsos will never get useful).
The back of the minifigs.
