The U.S. Army has used the Strategic Corporal term for their plan to equip ordinary squad leaders with advanced laser rangefinders to plot artillery fire. The need to conduct operations in this situation has significantly emphasised the importance of low level tactical leaders and led to the term "strategic corporal" being devised. One of the adjustments in the USMC is to move coordination of artillery down from the battalion to the company level. In the Battle of Mogadishu, as detailed in the book and film "Black Hawk Down", small-unit leaders on the ground continually had to make crucial decisions which had major impacts on not only the forces initially deployed on the mission, but to follow on forces as well.
