The Kargath Expeditionary Force (K.E.F.) 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.
Warlord Goretooth sends adventurers to annihilate General Angerforge's men because they are ruthless killers, responsible for the mass murder of the 109th division of the Kargath Expeditionary Force.
