ROLES OF THE AUTOMATIC RIFLE
• Support rifleman
• Engage intermediate distance targets
• Heavy volume of fire
• Assault weapon in close quarters or entry procedures
CHARACTERISTICSOF FIRE
• Trajectory
• Maximum ordinate
• Cone of fire
• Beaten zone
• Danger space
• Dead space
CHARACTERISTICSOF FIRE
• Trajectory--path of projectile
– Almost flat at 300 meters or less
– Beyond 300 meters, trajectory is curved and becomes greater as range increases
CHARACTERISTICSOF FIRE
• Maximum ordinate
– Highest point trajectory reaches from muzzle to target
– Occurs at 2/3 of distance between gun and target
CHARACTERISTICSOF FIRE
CHARACTERISTICSOF FIRE
• Cone of fire– Pattern formed by several rounds in a
burst, each round taking a slightly different trajectory
– Caused by vibration of the gun or variations in ammunition and atmospheric conditions
CHARACTERISTICSOF FIRE
• Beaten zone-area where cone of fire strikes the ground• Changes when range to target changes
– Uniformly sloping or level terrain, beaten zone is long and narrow
– Beaten zone becomes shorter and wider as range to target increases
– Terrain sloping down and away, beaten zone becomes longer
– Terrain rising, beaten zone becomes shorter– Terrain has no great effect on the width of the beaten
zone
CHARACTERISTICSOF FIRE
CHARACTERISTICS OF FIRE
• Danger space-space between gun and target where trajectory does not rise above 1.8 meters
• Fired over level terrain – Danger space to 700 meters
CHARACTERISTICSOF FIRE
• Dead space-area that can’t be seen or covered by gun position– Caused by depressions, rises,
obstructions, etc.– Must be covered by a different weapon
position or other type of weapon ie. M203
RANGEDETERMINATION
• Position disclosure
• Required for reporting adjustment of fire

1. Prone position2. Right handed3. Feet spread, heels down4. Shoulder rest up
Grip• Right hand on grip• Left hand on cover• Weapon pulled into shoulder with
3rd and 4th fingers of the shooting hand
Aiming• Sight alignment
1. Front-sight blade centered in rear sight aperture
2. Top of front-sight blade even with center of rear sight aperture
Aiming• Sight Picture
1. Top of front sight on center base of target
2. Eye focus on front-sight
Trigger Manipulation• Pull trigger and release• Control rounds in burst
Windage• Turn sight full left• Count number of clicks while
turning windage knob full right• Back off half the number of clicks to
the left
Elevation• Turn sight full up• Count number of clicks while
turning sight full down• Back off half the number of clicks
