TBS PHASE 3 Exam Questions and
Answers With 100% Complete Solutions
(2026 Update)
MG Fighting Positions + advantages of each - Correct Answer --L shape: When only
one sector of fire is assigned, only one half of the position is dug
-T shape: The most preferred position to employ. This position will provide both
primary and secondary sectors of fire.
-U shape: The open end of the horseshoe is toward the enemy (see diagram
below). This allows for easy 180-degree t
Classifications of Offensive Fires - Correct Answer --ISO Maneuver
-ISO Isolation
-ISO assault
-ISO consolidation
Define ISO Maneuver - Correct Answer -The machinegun unit will suppress the
maneuver unit's immediate objective to allow the unit to move into position to
conduct the final assault.
,Define ISO Isolation - Correct Answer -The machinegun unit will suppress any
enemy unit that can interfere with the maneuver element advance. It is implied
with this role that the machinegun unit be prepared to suppress or neutralize
previously unknown enemy units that may unmask during the attack.
Define ISO Assault - Correct Answer -The machinegun unit will suppress the
maneuver unit's immediate objective. These fires will be focused on a portion of
the objective that provides the greatest threat to maneuver elements. The rate of
fire should be close to or at the rapid rate, with the desired effect being that the
enemy is unable to affect the assault element. Initially the volume of fire will be
greater in order to establish fire superiority.
ISO Consolidation: - Correct Answer -Machine guns are used to protect the unit's
consolidation and reorganization.
MORT Statement (Displacement Considerations) - Correct Answer --Method: By
unit or by echelon
-Objective- consolidate on objective or secondary support by fire location
-Route
-Time-plan for when we will need their fires again if displacing to a secondary SBF,
or how long we will be able to support consolidation while the machine gun
assets displace to the rest of the unit. Another important aspect is the signal plan
surrounding that displacement.
, Example MORT statement - Correct Answer --Defensive- Upon enemy crossing TL
Blue (Red Star Cluster) displace by echelon via the fastest route to alternate
positions and suppress the enemy IOT support the platoon's displacement to the
alternate battle position.
-Offensive- Upon maneuver securing the objective (Green Star Cluster) displace by
team via the maneuver route to the center of 1st platoon IOT support our
consolidation.
Final Protective Line (FPL) - Correct Answer -An FPL is a predetermined line of
grazing fire designed to stop an enemy assault.
Principal Direction of Fire (PDF): - Correct Answer -a predetermined line of
machinegun fire that covers the most dangerous avenue of approach to a
defensive position with either plunging or grazing fire, when possible, to produce
front enfilade fire.
ADDRAC - Correct Answer -Alert, Direction, Description, Range, Assignment,
Control
How to build MG Range Cards - Correct Answer -1.Gunner lays himself behind the
gun, sets his sights on the limit of grazing fire, and then lays the gun on an aiming
point along the FPL.
