So random attempt at proportional exaggeration mostly failed. Still wound up slightly believable despite trying to force myself to make an impossible top heavy character. So I give you P.F.C. Beeftank.

That gun is just some random bullshit I thought of which basically boils down to a 50 caliber rifle/pistol. It does not make sense, don't try to think it through. It has a cleaver on the underside which would have been a halberd were it not attached to a gun.
