Here is the latest Vehicle build, The Krash Wagon, a converted Police heavy response vehicle. The "front" end is the the one with the turret, but there is a driving station on either end so front is relative. I am figuring the turret will have a mounted grenade launcher and a water cannon converted to a Flamethrower. I haven't modified the turret yet. The Turret is from Old Crow Models 6mm line.
Here is a size comparison with one of Proxie Model's Trencher tanks. I have to say the Trencher Platoon deal is a great one 3 tanks for $10 plus shipping.
