26
Weapons Conditions: Weapons Free
Fire only at targets not identified as friendly IAW current ROE.
27
Weapons Conditions: Weapons Tight
Fire only at targets positively identified as hostile IAW current ROE.
28
Weapons Conditions: Weapons Hold
Fire only in self-defense or in response to a formal order.
29
General Vehicle Kill Criteria: K-Kill
Catastrophic Kill Damage to a system such that economic repair is not feasible and the system is only fit for cannibalization/salvage of parts.
30
General Vehicle Kill Criteria: M-Kill
Mobility Kill Damage to a vehicle so that the driver cannot maintain controlled movement.
31
General Vehicle Kill Criteria: F-Kill
Firepower Kill Damage to the vehicle main armament so that direct fire against a target cannot be completed. The damage cannot be repaired by the crew on the battlefield.
32
General Vehicle Kill Criteria: P-Kill
Personnel Kill The incapacitation of fighting troops in a vehicle.
33
Personnel Damage Criteria: Harassed
One aircraft has rounds on target for one pass. Harassed personnel will seek cover and maneuver.
34
Personnel Damage Criteria: Neutralized
Will normally disrupt and disorganize an attacking unit sufficiently to render the unit incapable of conduction an effective attack. Incapable of offensive action.
35
Personnel Damage Criteria: Destroyed
Effective engagement of an organized ground unit, rendering the unit incapable of performing any military mission. Incapable of defending themselves.
36
GAU-18 Emergency Procedures
1) Gun - Trained on Target (Wait 5 secs) 2) Gun - CHARGED 3) Gun - Fire IF GUN STILL FAILS TO FIRE 4) “LEFT/RIGHT GUN BENT” 5) Gun Power Switch - OFF 6) Gun - Clear (Within 10 secs) **IF NOT CLEARED WITHIN 10 SECS, WAIT 5 MINS TO FIRE AGAIN**
37
Weapons Employment Requirements
1) Visual Survivor/Friendlies 2) Tally Threat 3) WEZ Deconfliction Met 4) Position Call - IN
38
Types of Fire
Hover, Running, Diving
39
Weapons Employment Fundamentals
Control Flexibility Fire and Maneuver Surprise Timing Exploitation
40
Additional Considerations
- Always assume area is hostile - Recon the objective area - Do not lose the survivor - Avoid flying through gun to target line - Do not do the enemy’s job for him - Threat versus target
41
Weapons Employment Patterns: L-Attack
100 ft AGL, 0.7 - 0.8 DME separation, pop up max rate climb, 1.2 NM from target, 6 degree dive
42
Weapons Employment Patterns: Racetracks
Two parallel legs connected by 180 degree turn. Max rate turns. 0.2 - 0.3 DME spacing. 70-80 KIAS. 10 to 20 second firing legs.
43
Weapons Employment Patterns: Dogbones
K Template, spacing 0.5 - 0.8 NM. 70-80 KIAS. Firing axis should be 15-20 seconds long.
44
Weapons Employment Patterns: U-Attacks
0.1 to 0.2 NM
45
Weapons Employment Patterns: Randoms
46
Field of Fire: Azimuth
0 to 171 degrees
47
Field of Fire: Elevation
Nose: 0 degrees Beam: +3 degrees Tail: +6 degrees
48
Field of Fire: Depression
Nose: -51 degrees Beam: -48 degrees Tail: -45 degrees

54
Types of Fire: Hover
Any engagement conducted below ETL. (effective translational lift)
55
Types of Fire: Running Fire
An engagement from a moving helicopter flown above ETL with an attack attitude less than 10 degrees nose low.
56
Types of Fire: Diving Fire
An engagement from a moving helicopter that is in a diving profile, more than 10 degrees nose low.
57
Weapons Employment Patterns
- Racetrack - L-Attack - U-Attack - Dog Bone - Random
58
Ballistics
- Interior - Exterior - Aerial - Terminal
59
Ballistics: Interior
Deals with characteristics that affect projectile motion inside the barrel
60
Ballistics: Exterior
Deals with characteristics that influence the motion of the projectile as it moves along its trajectory.
61
Ballistics: Aerial
Rotor Downwash, angular rate, spin-stabilized projectiles.
62
Ballistics: Terminal
The characteristics and effects of the projectile at the target.
63
Minimum Safe Distance (Training) per JFIRE
No friendlies within 500 meters of intended target
64
Ricochet Fan (Training) per JFIRE
No ground personnel with +/- 30 degrees of Final Attack Heading out to 3000 meters
