A few years ago, I got the bug to try something else that nobody had every seen or thought of before. Right about that time, Hasbro had released a basic Humvee that was basically a chassis. Immediately in my head, I thought it was the perfect canvas to customize.
My first concept was quickly sketched on a notepad and I wanted it to bristle with guns. The SF gun trucks in use at the time were completely open and quite vulnerable. My idea was to take the ambulance version of the Humvee, armor it, and arm it.
This is my original concept sketch for what would become a 1:6 scale model of a concept Gun Truck.
