Before leaving for Iraq, Petraeus recruited a number of highly educated military officers, nicknamed "Petraeus guys" or "designated thinkers", to advise him as commander, including Col. Mike Meese, head of the Social Sciences Department at West Point and Col. H.R. McMaster, famous for his leadership at the Battle of 73 Easting in the Gulf War and in the pacification of Tal Afar more recently, as well as for his doctoral dissertation on Vietnam-era civil-military relations titled "Dereliction of Duty". While most of Petraeus's closest advisers are American military officers, he also hired Lt. Col. David Kilcullen of the Australian Army, who was working for the US State Department. Kilcullen upon his return from Iraq published "The Accidental Guerrilla", and has discussed the central front of the war and lessons learned in Iraq in "The Washington Post".
