We have here my Academy kit,Callsign Models conversion kit and Masterclub tracks. It is built to resemble a troop cmds wagon without the turret as the 0.50cal was preferred due to the extra firepower I believe.
Hope you like it! Just beware if you plan on using the Masterclub tracks they are meant for the AFV kit so you will have to widen the drive sprockets to get them to fit!
