U.S. Army Organization and Doctrine: The basic composition of the triangular division was three infantry regiments and a variety of combat and combat support troops at the division level (see figure 1). Taken together, the weaponry within a triangular division gave commanders at all levels vast amounts of firepower. The division artillery was foremost in combat power among the assets found at division level. The division artillery had four battalions-three 105-mm howitzer battalions with twelve guns each and a 155-mm howitzer battalion with twelve guns. The standard infantry regiment, the next major command below division level, consisted of three infantry battalions, an antitank company, a cannon company, a headquarters company, a service company, and a medical detachment. The next lower organization was the infantry battalion. Three rifle companies, a heavy weapons company, and a headquarters company comprised an 871-man battalion. The rifle company consisted of 3 rifle platoons, a weapons platoon, and a small headquarters section and had a total manpower strength of 6 officers and 187 enlisted men. The weapons platoon was armed with two .30-caliber and one .50-caliber machine guns, three 60-mm mortars, and three 2.36-inch bazookas. Three infantry squads comprised a rifle platoon. Each rifle squad consisted of twelve men armed with ten M1 Garand rifles, one Browning automatic rifle, and one M1903 bolt-action Springfield rifle. Despite the awesome, aggregate firepower of the weapons within a triangular division, the lifeblood of the infantry division was the 5,211 officers and combat infantrymen who manned its 27 rifle companies.3 Russell Frank Weigley, Eisenhower's Lieutenants: The Campaign of France and Germany, 1944-1945 (Bloomington: Indiana University Press, 1981), p. 24. http://www.ibiblio.org/hyperwar/USA/CSI/CSI-Bocage/#2
