26STOPPAGES AND MALFUNCTIONS IMMEDIATE ACTION Within 10 secondsBolt to rearRound ejects -- continue
27STOPPAGES AND MALFUNCTIONS Remedial – Cold Barrel Round not ejectedHold handle to rear Open cover Remove ammo Inspect/clear weaponRound in chamberClose cover Attempt to fire
28STOPPAGES AND MALFUNCTIONS Remedial – Hot Barrel Remedial – Hot BarrelDuring combat, wait 5 seconds because of the possibility of a “hangfire” before applying remedial action. During training, wait 15 minutes before clearing a hot weapon and applying remedial action.

32OVERVIEW PERIOD II Roles of the automatic rifle Characteristics of fireRange determination/Lateral distance measurementPrinciples of fireEngagement of visible targetsLimited visibilityPredetermined fires
33ROLES OF THE AUTOMATIC RIFLE Support riflemanEngage intermediate distance targetsHeavy volume of fireAssault weapon in close quarters or entry procedures
34CHARACTERISTICS OF FIRE TrajectoryMaximum ordinateCone of fireBeaten zoneDanger spaceDead space
35CHARACTERISTICS OF FIRE Trajectory--path of projectileAlmost flat at 300 meters or lessBeyond 300 meters, trajectory is curved and becomes greater as range increases
36CHARACTERISTICS OF FIRE Maximum ordinateHighest point trajectory reaches from muzzle to targetOccurs at 2/3 of distance between gun and target
38CHARACTERISTICS OF FIRE Cone of firePattern formed by several rounds in a burst, each round taking a slightly different trajectoryCaused by vibration of the gun or variations in ammunition and atmospheric conditions
39CHARACTERISTICS OF FIRE Beaten zone-area where cone of fire strikes the groundChanges when range to target changesUniformly sloping or level terrain, beaten zone is long and narrowBeaten zone becomes shorter and wider as range to target increasesTerrain sloping down and away, beaten zone becomes longerTerrain rising, beaten zone becomes shorterTerrain has no great effect on the width of the beaten zone
41CHARACTERISTICS OF FIRE Danger space-space between gun and target where trajectory does not rise above 1.8 metersFired over level terrain – Danger space to 700 meters1.8 METERS IS AVERAGE HEIGHT OF TARGETSOME AREAS BETWEEN GUN AND TARGET MAY NOT HAVE DANGER SPACE
42CHARACTERISTICS OF FIRE Dead space-area that can’t be seen or covered by gun positionCaused by depressions, rises, obstructions, etc.Must be covered by a different weapon position or other type of weapon ie. M203
43RANGE DETERMINATION Position disclosure Required for reporting adjustment of fire
44RANGE DETERMINATION METHODS – Pacing Appearance of Objects Method 100 meter unit of measurePacingAppearance of Objects Method
45PRINCIPLES OF FIRE Types of targets Point Area Linear Deep Linear with depth
