So the plan is pretty clear for the two mega wagons I feel. As far as boys in the wagons go, they will either stay and shoot or jump to objectives will the tanks roll. I like them for how situational they can be! I am how ever open to trying something I have never used. Nob bikers. If there is a cool way to fit them in, but that could be more for another list. Over all I made the suggested changes and would like to see what you folks think
