TBS PHASE 3 EXAM SCRIPT 2026 FULL
QUESTIONS AND CORRECT ANSWERS
ALREADY PASSED
◉ Cone of Fire. Answer: pattern of each round fired due to vibration.
tolerances of ammo, and weapon shooter
◉ Beaten Zone. Answer: Elliptical pattern formed on the ground or
target by the striking rounds.
◉ Dead space. Answer: target or enemy drops below line of aim or line
of sight
◉ Danger space. Answer: 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. Answer: danger space confined to the beaten zone
◉ Grazing fire. Answer: 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. Answer: Fires relievers on flanks of target. Where
target is oriented 90 or more degrees away from firing unit
◉ Frontal fires. Answer: fires delivered on the front of a target, when the
target is oriented on the firing un
◉ Oblique Fires. Answer: fire delivered on the oblique of a target, when
the target is oriented between 0 and 90 degrees to the firing unit.
◉ Enfilade Fire. Answer: 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. Answer: 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. Answer: Interlocking fires:
reinforce and double the firepower employed across the units frontage.
, ◉ Employment Principles (PICMDEEP) C. Answer: Coordination of
fires: dictates use of appropriate weapons to fire on appropriate targets.
◉ Employment Principles (PICMDEEP) M. Answer: 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. Answer: Defilade: allows us
to fire the gun behind the mask of terrain outside the effects and
observation of the enemy.
◉ Employment Principles (PICMDEEP) E. Answer: Enfilade: the long
axis of the beaten zone coincides with the long axis of the target.
◉ Employment Principles (PICMDEEP) E. Answer: Economy: utilize
the appropriate weapons systems in accordance with the threat.
Correlates with engagement criteria.
◉ Employment Principles (PICMDEEP) P. Answer: 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.
