TECHNIQUE OF MACHINE GUN FIRE DIRECT LAYING
1. The angle between the axis of the bore and the line of sight is the angle of elevation 2. The highest point reached in the trajectory is called the Max. ordinate 3. The pattern made by the cone of fire as it strikes the ground is called the beaten zone. Only 85% of the shots are considered effective. 4. The size of the beaten zone is affected by the range and by the slope of terrain at the point of impact. 5. The length of the beaten zone becomes shorter when the trajectory falls at right angles to the ground. 6. Machine gun fire may be classified with respect to the gun, the target, and the ground.
