The Civil War was not all about contolled company fire. Just a few examples would include the fight atop Little Round Top, Devils Den, Shiloh, Franklin, Chickamauga, Alatoona Pass, Bentonville and countless other smaller actions. These did involve company fire but also individuals firing at individuals firing more than a few rounds. "Triggger Time" is a very valid part of a historic reenactment or recreation of a historic battle.
