Mortars are very light and effective artillery weapons, differing from classic works mainly by mounts. They are easy to move and do not need long time to prepare fire. They are designed primarily as an accompanying weapon of infantry to destroy manpower, some uncovered targets, but also resistant targets. They shoot exclusively in the upper group of angles. The smooth barrel does not slip during the shot and the pressure of the gases on its bottom is transmitted by the bearing to the terrain.
