"RE-GEN-ER-ATE!" (Dalek Medic)
This formerly Tier 4 Dalek has been fully upgraded and suited for combat healing in Tier 10 so you can keep on EXTERMINATING when the going gets tough!
It is comprised of two main parts: The outer shell, or "body armor", and a central pillar to which the six Nanotech Disruptors on the sides and the pilot seat are attached. The tank tracks do not transfer damage to this central pillar when destroyed, but are attached to the underside or "chassis" of the outer shell. This makes this Dalek Medic a frustrating opponent to a rail-gunner because once one side of the outer armor is destroyed, it can simply turn and face the opposite direction and still be able to heal just as effectively.
Not to mention the fact that it looks lovely in black :)
