K3 Bruiser

K3 Bruisers are the guards from the goblin town of K3 (hence their name), in the Storm Peaks. They are to both Alliance and Horde, but will turn  to anyone who makes PvP action inside or near K3.

Protecting K3
The primary strategy used by the K3 Bruisers when engaging into combat is to immobilize their enemy and attack at distance, by shooting. Their shoot ability knocks the target a small distance backwards; once their opponent reaches a certain distance from K3, they retreat. This is used to prevent PvP action from occurring in K3 without having to kill the players involved.

Trivia

 * Because their shoot ability knocks enemies back until they are far away from K3, this makes the bruisers from this goblin town the most efficient neutral city guards. Unlike other neutral guards that kill players engaging in PvP, K3 Bruisers just boot them out of the town.
 * Although they were updated to the new Goblin model in World of Warcraft: Cataclysm, their gear doesn't allow people to easily see the differences.
