Commander Surestrike is a Tau Commander.
Shadowsun came to recommended Surestrike to command the Fourth Sphere of Expansion. However disaster struck due to an overload of the fleet's AL-38 Slipstream Modules, creating a wormhole that threw the expedition across much of the galaxy. Lost in an nightmarish alternate dimension for an unclear period of time, Surestrike's fleet eventually re-emerged into realspace and immediately attempted to re-contact the Tau Empire. His forces were eventually successful, and when the Fifth Sphere of Expansion reemerged at the other side of the Startide Nexus, he greeted Shadowsun personally to the new Tau bastion in the heart of Imperial space.[1b]
