Hmm, actually, I'm not sure if there was already a wiki page...

Anyways, maybe there should be a separate vehicle with the plow instead, as the mining vehicle there already is a repulsorlift, a plow would seem strange for it.  The other mining vehicle would need to be on tracks (not train tracks, tank tracks), and it could have seats on the side of it that are meant for miners but infantry could use them to fire from.  The plow truck would usually lead as to take the brunt of the enemy fire with the mine vehicle and tanks behind, and when the group comes to a minefield the mine truck drives ahead to clear.  It could also be able to ram enemy vehicles.

It would be similar to this Dreadlock from Starsiege, just the areas next to the cockpit would be passenger seats, it would have a lower profile, and a longer chassis.  There would also be a button for the driver to raise or lower metal shields to allow allies to fire from the seats or to protect them.

Drew one up...  Should I add a crane to the back that someone controls to repair vehicles?
But yeah, trying to come up with a name for it...  Mine Excavator?
