SdKfz 251/22- an SdKfz with a Pak-40 mounted on top. It would likely be used as a fast town killer, ambush weapon, and camp breaker. Might need the ENY of the T-34 lowered to 30 since this thing has no armor to speak of, but has a decent gun.
Would also give us a relativly easy to add GV that will let us see how limited traverse would affect other TD's, and wether or not it might merit a reduction in perk cost, or even if this type of thing is something we want.
