Part of Crushcog's Arsenal.
Crushcog's Arsenal is an area in Dun Morogh between Gnomeregan and Ironforge. It is located in front of the massive, locked gate of a Hangar-style building.
It is inhabited by Irradiated Technicians, Crushcog Battle Suits, and Repaired Mechano-Tanks.
The area comes into play in the quests [1-30] Crushcog's Minions and [1-30] No Tanks!. Although there are Rocket Defense Turrets and Gnomeregan Recruits nearby, they do not appear to be involved.
