TBS Phase 3 Exam Questions with Verified Solutions Rated A+
Trajectory - Answers arching flight path of the round from the muzzle of the weapon to the target
Cone of Fire - Answers pattern of each round fired due to vibration. tolerances of ammo, and weapon
shooter
Beaten Zone - Answers Elliptical pattern formed on the ground or target by the striking rounds.
Dead space - Answers target or enemy drops below line of aim or line of sight
Danger space - Answers the area between the muzzle and the beaten zone where the bottom of the
cone of fire does not rise above 1.8 meters (the height of an average standing man).
Plunging Fire - Answers danger space confined to the beaten zone
Grazing fire - Answers center of the cone of fire does not rise more than one meter off the deck. This is
the most effective type of fire we can employ, and we will always seek a position where we can bring
the greatest amount of grazing fire upon the enemy.
Flanking Fires - Answers Fires relievers on flanks of target. Where target is oriented 90 or more degrees
away from firing unit
Frontal fires - Answers fires delivered on the front of a target, when the target is oriented on the firing
un
Oblique Fires - Answers fire delivered on the oblique of a target, when the target is oriented between 0
and 90 degrees to the firing unit.
Enfilade Fire - Answers the long axis of the beaten zone coincides with or nearly coincides with the long
axis of the target. This class of fire is either frontal or flanking and is the most desirable class of fire with
respect to the target, because it maximizes the use of the beaten zone.
Employment Principles (PICMDEEP) P - Answers Pairs: we attempt to employ machine guns in pairs at all
times. This allows us to duplicate fires to ensure continuous fire support even if one gun goes down. This
also gives us "talking guns", giving us constant fires on the targe
Employment Principles (PICMDEEP) I - Answers Interlocking fires: reinforce and double the firepower
employed across the units frontage.
Employment Principles (PICMDEEP) C - Answers Coordination of fires: dictates use of appropriate
weapons to fire on appropriate targets.
Employment Principles (PICMDEEP) M - Answers Mutual support: the weapons systems need to be able
to support each other. If one weapon is overrun or fails, the other weapon needs to be able to fire the
mission.
, Employment Principles (PICMDEEP) D - Answers Defilade: allows us to fire the gun behind the mask of
terrain outside the effects and observation of the enemy.
Employment Principles (PICMDEEP) E - Answers Enfilade: the long axis of the beaten zone coincides with
the long axis of the target.
Employment Principles (PICMDEEP) E - Answers Economy: utilize the appropriate weapons systems in
accordance with the threat. Correlates with engagement criteria.
Employment Principles (PICMDEEP) P - Answers Protection: obvious considerations need to be taken in
the construction of machine gun positions in order to ensure maximum survivability of the crew. Cover
and concealment are critical.
