The author utilized the Battle of Fallujah (Operation AL FAJR/PHANTOM FURY) as a case study to illustrate how Marines effectively used money to influence counterinsurgency operations. During the Battle of Fallujah, Marine civil affairs successfully used money as an important weapon against insurgents. Since insurgents derived strength from the civilian population, the objective was to draw local Fallujans away from the enemy. To accomplish this, Marine civil affairs focused on the needs and grievances of the local populace by using money to solve problems for the Fallujans and facilitate relief and reconstruction. To achieve effectiveness, the Marines developed a broad understanding of the funding pipelines available in Iraq and established a responsive system for employing money rapidly.
