|
Trajectory |
The arching flight path of the round from the muzzle of the weapon to the target |
|
|
Ordinate |
Elevatio nof the flight path of the round above LOS |
|
|
Max Ordinate |
Max elevation of that round above the LOS, usually 2/3 of the distance to the target |
|
|
Cone of fire |
(M240B)
Pattern of rounds that make a 2mil wide cone of lead |
|
|
Beaten Zone |
2 mil wide zone where the rounds will land |
|
|
Dead Space |
Occurs anytime the enemy or target drops below the line of aim/line of sight of the target(a product of terrain) |
|
|
Danger Space |
Any space up to 1.8meters above the deck |
|
|
Plunging Fire |
Where the danger space is confined to the beaten zone. When firing from the high to low ground. Effects of rounds are limited to the beaten zone where those rounds hit the deck. |
|
|
Grazing fire |
Where the center of the cone of fire does not rise more than 1meter above the deck. |
|
|
Flanking Fire |
Fires delivered on enemy oriented 90 degrees or more away from firing unit |
|
|
Frontal Fire |
Fires delivered in front of target, when target is oriented on the firing unit. |
|
|
Oblique fire |
Fires delivered on taret when the target is oriented between 0 and 90 degrees of the firing unit. |
|
|
Enflilade fire |
The long axis of the beaten zone coincides with the long axis of the target, can either be classified as frontal enfilade or flanking enfilade |
|
|
Rixed fires |
Fires delivered on point target without moving the gun. |
|
|
Traversing target |
Fires delivered on a wide target requiring changes in direction. Beaten zone is adjacent. |
|
|
Searching |
Fires delivered on a target in depth, requiring change sin elevation. Beaten zone is adjacent. |
|
|
Traversing and searching |
Fires delivered on oblique target req. changes in both direction and elevation. Beaten zone is adjacent. |
|
|
Swinging Traverse |
Fires delivered on targets with major changes in direction but little to no changes in eleveation. Fired at the cyclic rate of fire. Beaten zone not need to be adjacent. |
|
|
Fre gun |
Fires delivered against moving targets req. major changes in direction and elevation. Beaten zone not need to be adjacent. |
