Direct fire

As a direct shot refers to a shot with firearms, in which the target can be directly, optical or electronic sights, aimed at. In contrast, there is an indirect shot, if indeed the location of the target is known, but it can not be targeted directly, but the direction and the increase of the tube must be calculated.

The fired projectile follows a parabolic trajectory, which goes beyond the line of sight and drops again. After a projectile exits the tube, it is subject to the air resistance, which slows the projectile of the force of gravity that pulls the projectile down, and other atmospheric influences. The doctrine of ballistics describes the trajectory.

The line of sight is true because of the trajectory of the projectile does not match the bore axis of the tube.

The elevation of the trajectory over the line of sight depends on the set distance of the visor and the panache of the projectile.

With a correctly adjusted distance to the trajectory of the projectile and the line of sight intersect at the target.

Example of use

A moving target in a man's height or a rapidly approaching Slate corresponding amount is targeted. First, the target is still about 600 meters away. The shooter would have the sight to 600 meters set, he wanted to aim at the target center. Falls below the approaching target the 400-meter, 200 - meter line, etc., the visor would have quickly and are constantly adjusted to the new distance, providing fast and correct range estimation.

If the calculated distance of the direct income but also for example 600 meters, so the shooter can meet the approaching target at any distance, without adjusting the sights as soon as it comes closer than 600 meters. Targeted Zielaufsitzend, the target is thus made ​​even at a distance of, for example, only 100 meters even though the shooter does not change the visor setting of 600 meters.
