As the range to the target increases, the elliptical shape of the beaten zone becomes shorter and wider.
When firing Onto slopes, the beaten zone becomes shorter, but retains the same width.
Plunging Fire--this is fire in which the angle of the fall of the rounds with reference to the' slope of the ground is such that the so-called "danger space" for friendly troops is practically confined to the beaten zone and because of the slope of the ground is materially shortened.
Frontal Fire--the long axis of the beaten zone is in direct line with the forward movement of the target.
Oblique Fire--fire in which the long axis of the beaten zone is at an angle, but not 'a right angle, to the long axis of the target.
This is fire in which the long axis of the beaten zone coincides with the long axis of the target, This is the single most desirable class of machine gun fire with respect to the target, because it makes the most effective use of the beaten zone.
Lift fire--In direct fire, the command to raise the cone of fire so that the beaten zone strikes the target, but the space between the target and the firing weapons is safe for maneuver by friendly forces.
Shift fire--The command to move the cone of fire in a direction away from a friendly maneuvering force so that enemy forces continue to be struck by the beaten zone at the same time the friendly unit moves.
