1. What is the primary mission of the Marine Corps rifle squad in offensive operations?
Answer:
To locate, close with, and destroy the enemy by fire and maneuver, or to repel the enemy assault
by fire and close combat.
Rationale:
This reflects the doctrinal mission of Marine infantry units. FMF Officers must internalize
tactical fundamentals to effectively lead small units in both offensive and defensive roles.
2. What is the purpose of the Command and Control (C2) system in Marine operations?
Answer:
To enable the commander to understand, visualize, describe, direct, lead, and assess operations
effectively in support of mission accomplishment.
Rationale:
C2 is the backbone of all operations. FMF officers must understand how to employ C2 systems
(radio, satellite, digital networks) under various conditions to maintain unit cohesion and mission
tempo.
3. Define the principle of "Economy of Force" in maneuver warfare.
Answer:
Economy of Force is the allocation of minimum essential combat power to secondary efforts in
order to concentrate maximum effort on decisive actions.
Rationale:
FMF Officers must grasp the art of prioritization and resource allocation — understanding where
to accept risk and where to apply combat power decisively.
4. What are the three types of defensive operations?
Answer:
1. Mobile defense
2. Area defense
, 3. Retrograde
Rationale:
Each defense type serves different strategic objectives: Mobile focuses on destruction through
maneuver, Area on terrain denial, and Retrograde on delaying or repositioning. FMF Officers
must select and execute the right one based on mission and terrain.
5. What is the purpose of a Fire Support Coordination Center (FSCC) at the battalion
level?
Answer:
To plan, coordinate, and integrate all fire support (artillery, air, naval gunfire, mortars) for the
supported unit during operations.
Rationale:
FMF Officers must understand fire support doctrine and coordination to ensure fires are
effective, timely, and deconflicted with friendly forces — critical in joint or combined arms
operations.
6. During amphibious operations, what phase follows the planning phase?
Answer:
Embarkation phase.
Rationale:
Amphibious operations follow a defined sequence: Planning → Embarkation → Rehearsal →
Movement → Action (PERMA). FMF Officers must understand this sequence to synchronize
logistics and combat power deployment from sea to shore.
7. What does METT-T stand for, and how is it applied in operational planning?
Answer:
Mission, Enemy, Terrain & Weather, Troops & Support available, Time available.
Rationale:
METT-T is a framework FMF Officers use during the estimate of the situation. It drives tactical
decisions by identifying key factors affecting mission success and risk.
8. What is the minimum safe distance for friendly troops from a 155mm artillery round
using HE/PD fuse during training?
,Answer:
600 meters.
Rationale:
Knowledge of safety distances for indirect fires is essential to prevent friendly casualties during
training or combat. FMF Officers must apply this to fire support planning and danger close
coordination.
9. What are the six troop leading steps in BAMCIS?
Answer:
1. Begin the planning
2. Arrange reconnaissance
3. Make reconnaissance
4. Complete the plan
5. Issue the order
6. Supervise
Rationale:
BAMCIS is a fundamental leadership tool that ensures small unit leaders issue timely, informed,
and executable orders. FMF Officers must master it for rapid decision-making and decentralized
operations.
10. What is the operational purpose of MCDP 1 (Warfighting)?
Answer:
To articulate the Marine Corps’ philosophy of warfighting based on maneuver warfare and the
centrality of the human dimension in combat.
Rationale:
MCDP 1 is the foundational doctrinal publication every FMF Officer must internalize. It frames
all tactical and operational thinking, emphasizing initiative, tempo, and unpredictability in
combat.
11. What is the standard fire team formation and its purpose?
Answer:
Wedge formation – provides all-around security and flexibility, allowing rapid transition to
other formations.
, Rationale:
The wedge allows for 360° security and is optimal for movement through uncertain terrain. FMF
officers must understand small unit formations to effectively maneuver squads and fire teams.
12. What is the purpose of an Operations Order (OPORD)?
Answer:
To communicate the commander’s intent, mission, and scheme of maneuver, enabling
subordinates to execute with initiative.
Rationale:
An OPORD provides clarity and alignment. FMF Officers must be skilled in writing and
delivering orders under pressure using the five-paragraph format (SMEAC).
13. What is the maximum effective range of an M240B machine gun on a point target
(tripod)?
Answer:
800 meters (point target, tripod-mounted).
Rationale:
Understanding weapon capabilities is critical for planning support by fire positions and direct
fire engagements.
14. What are the three tactical tasks of an infantry unit in offensive operations?
Answer:
1. Attack
2. Exploit
3. Pursue
Rationale:
These reflect the doctrinal phases of offensive action. FMF Officers must recognize when to
transition from deliberate attack to exploitation and pursuit to maintain momentum.
15. What is the difference between cover and concealment?
Answer:
