Ten Ton Hammer has posted a "guide" to Wedge Rock Outpost. Containing information about quests and possible dangers, here's a snippet of information:

Wedge Rock Outpost is a defensive position situated as the name would indicate on a large rock overseeing a hostile area. All approaches are protected by elevation and heavy artillery not to mention the full compliment of AFS soldiers just inside. This is not a control point so there is no danger of being attacked and you'll find a medic, vendor, and teleport pad for your convienience. The purpose of your visit here will be a series of missions we're going to walk you through.
