Line of Sight is?
an imaginary line, from the firers' eye, through the sights, to the point of aim on the target.
A burst of fire is?
a number of successive rounds fired with the same elevation and point of aim, when the trigger is held to the rear.
Number of rounds in a burst?
Can vary depending on the rate of fire employed.
Factors that affect a burst of fire
The gunner and rate of fire.
The gun and ammunition.
Clarity of target.
Air / weather.
Distance.
Trajectory is?
The curved path the round takes
during its flight.
Maximum ordinate is?
The highest point above the line of sight which a projectile rises during its' flight.
Maximum ordinate occurs?
about 2/3rds of the distance from the weapon to the target and increases with the range.
The Cone of Fire is?
The pattern made by a group of rounds resulting from a burst of fire.
The Cone of Fire pattern is caused mostly by?
the vibration of the machine gun and variations in ammunition and atmospheric conditions
The Beaten Zone is?
The elliptical pattern formed on the ground or target by the striking rounds.
Effective beaten zone = ?
85% of rounds
Density of Beaten Zone decreases _____ ___ ___

Free-Gun Fire
Grazing Fire Defined
Cone of fire rises less than 1 meter above ground. On level terrain, grazing fire out to 600 meters. Danger space is from the end of the barrel out to the last round in the beaten zone
Plunging Fire Defined
Occurs when the danger space is within the beaten zone. Results in a loss of grazing fire at any point along the trajectory
Frontal fire Defined
occurs when the long axis of the beaten zone is at a right angle to the front of the target.
Flanking fire Defined
occurs when the gunner fires at the side of the target.
Oblique fire Defined
Occurs when the long axis of the beaten zone is at an angle other than a right angle to the front of the target.
Enfilade fire Defined
Occurs when the long axis of the beaten zone coincides or nearly coincides with the long axis of the target.
Fixed Fire Defined
Fire delivered against a stationary point target when the depth and width of the beaten zone covers the target.
Traversing fire Defined
Fire distributed in width by successive changes in direction.
Searching fire Defined
Fire is distributed in depth by successive changes in elevation.
Traversing and searching fire Defined
Is a combination in which successive changes in direction and elevation.
Free-gun fire Defined.
Fire is delivered against targets requiring major changes in direction and elevation that cannot be applied with the T&E mechanism.
