do you know how long the A-10 gattling gun is? You might be hard pressed to get it to fit into the M1A1 lol ! the A-10 was built around that gun ! It isnt small! lol

But would a ground based version need such a long barrel to achieve comparable accuracy? As an urban assault vehicle, the distances that could be seen would be much shorter. Why not build a shorter barreled version that could be put on a tank?

its not so much that the barrel is long.. the whole damn thing is HUGE! im sure you could make it work... it would be difficult! but, I think it would be better if they just upgraded some NEW AC-130's with this weapon :) have it coming out of the bottom and the gunner looking thru a camera, with night-vision and thermal.

Why bother with a GAU-8? Go with a the Hughes Chain Gun from the Apache or a 20mm Vulcan. Or maybe quad 50's or or 20mm or twin 30mm or 40mm (IIRC Dusters did some pretty good work in Vietnam and the ZSU-23-4 was real threat against both air and soft targets). The GAU-8 is massive overkill for most urban work - remember, it was designed to kill tanks! Heck, maybe we could rework the Sgt. York (a total loser as ADA) into an infantry support vehicle.

Also these weapons are lighter, allowing for more armor or more ammo.
