The Bullock is an automated machine tasked with suppressing the enemy with its firepower to enable ground troops more flexibility on the ground. It has aerial denial capabilities against enemy drones and aircraft in one respect, and good line of sight to engage infantry. They serve as auxiliaries that walk alongside larger ground machines.

I took the bullock out of the dust-bin and revised it to look more contemporary; refer to old one to see changes.
