Which round has a purpose specifically for drills and testing purposes?

The dummy round is specifically designed for drills and testing purposes, serving as a non-firing item that mimics the weight and size of a live round without having any explosive components. This allows personnel to practice handling, loading, and performing operations as they would with a live round, but without the risk associated with actual ammunition. Dummy rounds enable teams to train in realistic conditions, ensuring that they build muscle memory and familiarity with their weapons systems in a safe environment.

Live rounds are intended for actual firing and use in combat situations, making them unsuitable for training where safety is a priority. Blank rounds are made to simulate the sound and muzzle flash of a firing weapon, but they don't provide the benefits of training with the actual mechanics of a round. Incendiary rounds are designed to start fires and cause destruction, which is again not appropriate for training and drills. The dummy round's sole purpose in training makes it the most appropriate choice for such activities.
