Unit S is a group that includes twelve soldiers who were gathered together to storm a Scourge ziggurat outside a plagued nerubian city. They were formed by Counselor Talbot, the same 'man' who chose Thassarian to be their leader.
- In Death Knight, it appears Thassarian raised Lurid from the corpse of a solder of Unit S.
- Private Brau's claims are further confirmed when it is revealed that Counselor Talbot's plan was to make sure that Thassarian would have never made it back to the keep alive.
If Old Man Colburn is right, the unit could have been named from:
While Sentinel Hill does start with S, the town and surrounding area is under the purview of the Westfall Brigade, which joined the Stormwind Army as an official outfit in WotLK and has its own encampment in Grizzly Hills.
Alternatively, its name could be an abbreviation from "strike force" as Counselor Talbot called it.
