Cover (artillery)
The term cover (as a verb : cover lying ) means in guns that the impacts of the shells of a volley lie both in front of and behind the targeted target without hitting it. In particular, in the case of coordinated fire from a battery or a gun- armored warship, covering the grenades was the aim initially aimed at in combat, as the first real hits usually followed immediately afterwards (so-called zeroing in on a target), since only the dispersion prevented the hit from being hit. In fact, however, impacts that are already covered can cause massive damage to the target due to pressure waves or splinter effects. With modern guns, the first hit probability is so high due to their refined fire control and the use of sometimes homing or radar-guided grenades that covering hits are no longer aimed at as a "stage target" for the actual effect on the target.
