Just as machine gun teams always took priority in the last couple of wars, I wouldn't expect this thing to have a long life on the battlefield.
So this juggernaut is equipped with a lot of large caliber weapons, capable of being used for close range.
The only drawback is that according to the rule books, you don't fire on personnel with anything larger than a 7.62x59mm. Not much fun...
But you can kill TONS of Abrams and down a couple of Cobras!
