I didn't read up on this thoroughly before i started farming it. I just read the few names in the first tents when you zone in that could drop it and I killed there for about 3 hours and had no drops of this item. My roommate started to read everyone's comments and suggested we kill the guards over the bridge area. We killed those that guard the door in pairs at either end of the bridge and in the building by where you zone in about 8 times and no drop. So then we moved to the squad leaders and got 3 drops out of 4 kills in a row. Then the next drop was on the 7th squad leader kill.
Squad Leaders for the win. This did not drop of any other mob on the list in many many clears.
