Okay, these tank-like engines of destruction just seem to plow through pretty much anything I throw at them which isn't high-valor spear-weilding wall-of-horsey-death type. I mean, I had Byzzie Emperor with 20 of them plow through 120 feudal sarges like tanks over Chinese protestors.

They just seem ridiculously overpowered -- I've seen them easily get 20-1 kill rates.
