Behold the Sturmpanzer II, Bison and SU-5, The M44's grand successors.

Draschel: M44 is a nice chassis though. And tier 6 is much different than tier 4 Bison, Sturm, SU5 are all terrible chassis, and tier 4 has alot of fast, small runty stuff harder to target than the stuff tier 6 has, like AT7, OI, M6.
