After years of developing the elite 75th Ranger Regiment's hand to hand program, he was assigned to the Ranger Training Brigade, the Combatives proponent at the time, to rewrite the Field Manual FM 21-150. Upon finishing this, it was published in 2002 as FM 3-25.150 (Combatives). He was asked by the 11th Infantry Regiment (a TRADOC unit) to develop a training course for their cadre. Advocacy for the Combatives doctrine was transferred to the 11th Infantry Regiment to follow him. An old, disused warehouse in Fort Benning, Georgia became the site of the school. Soon, units from around the Army were sending Soldiers to this course. Over the next several years, the program was developed around the idea of building virtually self-sustaining Combatives programs within units by training cadres of instructors indigenous to each unit. With the continued success of this approach, the school became the recognized source of instruction for the entire US Army.
