Soldiers assigned to Headquarters Support Company, Headquarters, Headquarters Battalion, U.S. Army North (Fifth Army) challenged their marksmanship abilities on the Engagement Skills Trainer at Joint Base San Antonio-Fort Sam Houston Feb. 22. Soldiers practiced firing and qualifying with the M9 pistol and M16 rifle to ensure every Soldier was familiar with the weapons. Once complete with qualification, Soldiers engaged in shoot/don't shoot scenario based training. Using the E.S.T. simulator has benefits of allowing firers the opportunity for increased training without the added cost of ammunition and other logistical requirements.
