When you have a large machine gun, it is very hard to hook it up to a motor cycle. So, what do you do? You get two motor cycles. But you can't go around with a huge gun and no armor, so you take sheet metal and metal bars and shield yourselves from the bullets that are sure to fly your way.
As the driver, you need to see much better. So, he gets full-on bullet-resistant glass on his side.
The gunner doesn't to see his side as much as he needs protection. So, he gets a big piece of sheet metal for protection. Also, some extra weapons on the door just in case.
Showing the gun...
...Moving up and down.
Our heroic drivers in front of their make-shift ride.
Without the armor.
Needless to say, the drivers would be doomed without all of that sheet-metal.
So, there it is. I hope you enjoyed. This is really my first attempt at a post-apoc MOC (as in not a dio.). Remember, it's all in the details, and happy MOCing!
