Good shots required coolness under fire; steely self-discipline; familiarity with such high-tech implements as telescopic sights, windage indicators, and ballistic instruments; a determination to improve themselves by constant training; and independence of thought and action. In Europe, where the ideology of mass-firepower had long held sway, soldiers were still treated as dull, disposable automatons and subjected to fearsome discipline to flog out any remnants of individual initiative. Civil War generals had fallen beneath the European spell; Church wanted to “re-Americanize” warfare.
