A dummy round is typically a trial shot fired by an artillery piece to test its accuracy and velocity before engaging the target. This type of round is often used at the beginning of a battle or during training exercises to gauge the effectiveness of the weapons system and crew. The dummy round serves as a precursor to live fire, allowing gunners to make necessary adjustments to their aim and firing techniques before unleashing a barrage on the enemy. By executing a dummy round, military personnel can ensure that their artillery piece is functioning properly and that they are on target for the actual engagement.
