I’ve spent the entirety of the last five minutes thinking about this thing, and the real pro move would to be making it a two person crew and to mount the main gun facing the rear so as to capture the momentum of the rounds as speed.

In this case, it’d probably be worth it to have a small machine gun for the forward facing “driver” to use, maybe with a rack of grenades/other thrown explosive on the front.

So anyway, I’m sure this comment will get me onto some kind of FBI/NSA/CIA watch list.
