Shooting at targets on the ground that vary in position, direction, distance, and speed
Shooting at moving targets on the ground, shooting at targets on the ground that are constantly changing in position, direction, distance and speed. Since the target position is not fixed, and the running direction, distance and speed often change, in order for the projectile to hit the target, the lead must be taken. When shooting at a target moving in a horizontal direction, you must take the lead in front of the target movement and move the aiming line to the front of the target. When shooting at an oblique moving target, multiply the horizontal advance by the oblique angle function. When shooting at a moving target in the longitudinal direction, the infantry machine gun is usually equipped with a distance gauge due to its low trajectory, and the shooting is carried out by raising or lowering the aiming point. The artillery shoots at tanks and cars that move in the longitudinal direction. Because the target moves faster, it is generally shot by changing the reticle.
