HKB-3 hunter-killer droid

The HKB-3 hunter-killer droid was a battle droid produced by Baktoid Combat Automata prior to the Invasion of Naboo.

Characteristics
HKB-3 droids were easily modified hunter-killer droids. They had square heads and were equipped with rapid-fire blasters. They relied on a Central Control Computer to coordinate their operation. This feature made them effective at tracking a target because they could easily coordinate with each other when sent out in groups. Individually they had poor targeting abilities, but in a group, if one droid homed in on a target, all droids in the patrol group could coordinate their fire on the same coordinates to maximize their effectiveness.
