Kargath Expeditionary Force
From WoWWiki
The Kargath Expeditionary Force is a military exploration group based out of the outpost of Kargath in the Badlands of Khaz Modan. Sent by order of Thrall himself - both to reinforce Kargath and to explore the arid region it was located in - the K.E.F. has made excursions through the region, including into the depths of Uldaman to discover why it was of more than a passing interest to the dwarves. They also dug a pass through to the Searing Gorge to reach Blackrock Mountain (the intent being to confront the false Warchief Rend Blackhand) but inadvertently set loose the Dark Iron dwarves.
