Grazing fire

When each bullet is fired, it will leave the barrel of the weapon at the axis of bore set from the angle of sight desired to strike the target area.

Maximum ordinate is the highest point of the trajectory, which is usually two-thirds the distance to the target from the weapon.

Depending on the caliber of the round being fired and the slope of the terrain, as well as the distance to the target, the bullet will maintain a semi-flat trajectory.

Any distance beyond that range will be considered plunging fire due to the arc (axis of bore plus angle of sight) needed to impact the target area.

In addition to keeping the enemy pinned down, anybody wounded or going to cover will fall into the line of fire, not out of it.
