TBS PHASE 3 FINAL TEST 2026
QUESTIONS WITH CORRECT
ANSWERS GRADED A+
◍ Defensive Planning - Develop Engagement Area.
Answer: a. ID all likely EN AoAsb. Determine likely EN SOMs and the
EMLCOA(which AoA will he use?)c. Determine where to kill the ENd.
Emplace weapon systemse. Plan/integrate Obstaclesf. Plan/integrate IDFg.
Conduct EA rehearsal
◍ Breaching fundamentals Secure.
Answer: The force secures the breaching site to prevent the enemy from
interfering with obstacle reduction and passage of the assault force through
the lanes created. Identifying the extent of enemy defenses is critical before
selecting the appropriate technique to secure the breach. In general, enemy
tactical obstacles are secured by fire and protective obstacles are secured by
force
◍ Plt Defense Order - SOM.
Answer: · Elements of Defensive SOM (TDOOTS)T - Type: - Area/BP
Perimeter, StrongpointD - Distribution of Forces: - ME, SE #1 , SE#2,
SE#3O - Orientation: - Cardinal direction of defenseO - Occupation: -
Crows foot, Bent L, combinedT - TCMs: - TRPs, TLs, RPs, etc.S - Security
Plan: - Stand-to, LP/OP, Patrols, Alert Posture
◍ Use of Terrain.
Answer: must exploit every aspect of terrain and weather to his advantage.
◍ Primary Role of Engineer in the Defense.
Answer: 1) Impede the mobility of the enemy2) Field Fortification3)
Provide general engineering tasks to amplify sustainability of supported
, unit.
◍ Example MORT statement.
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.
◍ Given a mission, a commander's intent, and a defensive position, select
command post (CP) location to facilitate command and control (C2)..
Answer: The CP is usually located behind the ME (the defensive position's
bid for success). Position should provide optimum C2 and observation. The
CP should be marked.
◍ 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
◍ What is the sustained rate of fire for the M2?.
Answer: Less than 40 rpm
◍ Target Precedence.
Answer: When engagement criteria is met by multiple targets
simultaneously, target precedence determines the order in which targets
should be engaged. Each weapon system is given target precedence in
accordance with its capabilities. Another control measure facilitating
decentralized execution, the platoon commander should develop target
precedence which maximizes weapons effects and which will most quickly
disrupt the enemy's scheme of maneuver. While engagement criteria tells
Marines WHEN to engage, target precedence tells Marines WHAT to
engage.
, ◍ Priorities of Leader's Recon.
Answer: Confirm location and orientation of enemy defense, identify CV,
identify an Assault POS, identify a SBF, identify routes and TCM's that
support SOM
◍ Counter-Mobility.
Answer: Counter-Mobility: Deny EN the ability to execute his plan•
Obstacles: Existing (Natural, Cultural) and Reinforcing (Constructed,
Demolitions, Mines, Contamination, Expedient). Classified as Protective or
Tactical. o FOCDPIG• Covered by Fires: Obstacles are useless unless
they're integrated w/ fires• Observed• Concealed: Employed for surprise•
Employed in Depth: Series of obstacles instead of a single obstacle•
Protected by early warning/anti-handling devices• Integrated w/ existing and
other reinforcing obstacles: Must support tactical plan• Non-Geometric:
Kid's drawingo Wire: Tactical (XXXX), Supplementary (==XX==XX==),
Protective (XXXX)o Tactical Tasks: Disrupt, Turn, Fix, Blocko Obstacle
Plan: Obstacle Responsibilities, General Location, Directed/Reserve,
Special Instructionso Constructed Obstacles• Concertina Wire:
Anti-Personnel. Triple is the strongest• Tanglefoot: Disrupt EN foot
movement• Four-Strand Cattle Fence: Quickly constructed protective
obstacle• Knife Rest: Roadblock that can be easily moved• Log Crib:
Triangular is strongest. Anti-Vehicular• Eleven-Row Wire Obstacle:
Anti-Personnel• Abatis: Anti-Vehicular or Personnel. Can be interlaced w/
wire• HESCO: Protective vs SA fire. Can take (1) IDF round before
replacement
◍ Supplementary Position.
Answer: allows a unit to address unexpected enemy schemes of maneuver.
◍ What classification of machinegun fire deals with fixed, traversing, and
searching fires?.
Answer: In relation to the gun
◍ Fire Support Coordination Line (FSCL).
Answer: Expedite surface-to-surface AND air-to-surface attack beyond
