Part of the shield or tank factorys, some sort of heavy ramming vehicle. All units and structures would be affected and it would attack though using a rocket (for acceleration) with a 30 sec recharge. Damage would be done purely though speed, it would get much much reduced collision damage and would ever be able to knock down terraformed walls. Health would be kind of around the Minotaur and it would be fantastic in assaults. Going very VERY fast; it would be able to fling units as a newton does- but by ramming.
I feel like zk is lacking a little in the fun weird units and with some balencing this would be a great addition!
