TBS Phase 3 Exam 2026 Questions and
Answers
Trajectory - Correct answer-The arching flight path of the round from the muzzle
of the weapon to the target.
Ordinate - Correct answer-Elevation of the flight path of the round above the line
of sight
Max Ordinate - Correct answer-The maximum elevation of that round above the
line of sight along its flight path. This distance is reached at 2/3 the distance to the
target
Cone of Fire - Correct answer-The pattern of a fired rounds based on vibration,
tolerances of the ammunition and weapon, and shooter positions.
Beaten Zone - Correct answer-The elliptical pattern formed by the impact of the
round
Dead Space - Correct answer-Occurs anytime the target (or enemy) drops below
the line of aim or line of sight.

,Danger Space - Correct 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 - 70").
Plunging Fire - Correct answer-Where the danger space is confined to the beaten
zone. Plunging fire is obtained when firing from high ground to low ground or low
ground to high ground.
Grazing Fire - Correct answer-Defines fire where the 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 Fire - Correct answer-Fires delivered on the flank of a target when the
target is oriented 90 or more degrees away from the firing unit.
Frontal Fire - Correct answer-Fire delivered on the front of a target, when the target
is oriented on the firing unit.
Oblique Fire - Correct 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 - Correct 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
Fixed Fire - Correct answer-Fire delivered on a point target. Little or no
manipulation of the gun is required to obtain and maintain effect on target.
Traversing Fire - Correct answer-Fire delivered against a wide target requiring
changes in direction.
Searching Fire - Correct answer-Fire delivered against a target in depth requiring
changes in elevation.
Traversing & Searching Fire - Correct answer-Fire delivered against an oblique
target requiring changes in both elevation and direction
Swinging Traverse Fire - Correct answer-Fire delivered against targets which
require major changes in direction with little or no change in elevation. Fired at the
cyclic rate of fire using the tripod.
Free Gun - Correct answer-Fire delivered against moving targets that require major
changes in both direction and elevation. The T&E is not used as the manipulation
is done by the Gunner.
