Strelets-R 0150 1/72 American Civil War US Infantry in Attack

The conventional narrative is that generals and other officers adhered stubbornly to the tactics of the Napoleonic Wars, in which armies employed linear formations and favored open fields over the usage of cover (whether constructed or natural in origin). Presumably, the greater accuracy and range of the rifle musket rendered that approach obsolete, and the Civil War armies' transition to longer battles in 1864 is taken by numerous scholars as proof of the new technology's transformative impact.
