Introduction
The M240 machine gun is the standard medium machine gun of the United States military,
serving as the primary automatic weapon for infantry, security forces, and naval security units.
The CENSECFOR M240 Machine Gun Operator Training Examination evaluates competency
across the essential knowledge domains required for safe and effective employment of this
weapon system. This examination is aligned with current TM 9-1005-313-10 technical manual
procedures, CENSECFOR training standards, OPNAVINST 3591.1 firearms qualification
requirements, and military firearms proficiency directives. Successful completion demonstrates
mastery of the Four Universal Safety Rules, M240 mechanical operation and maintenance, crew
coordination, ammunition management, loading and firing procedures, stoppage clearance
protocols, preventive maintenance practices, and tactical fire control principles. The M240's role
as a force protection and area suppression weapon demands that operators possess both technical
proficiency and the tactical judgment to employ the weapon system within rules of engagement,
safety constraints, and mission requirements.
Examination Questions
Domain: Firearms Safety & Range Operations
Q1: Which of the following correctly lists all Four Universal Safety Rules that must
be applied whenever handling the M240 machine gun?
A. Treat every firearm as if it is loaded; never point the muzzle at anything you are not
willing to destroy; keep your finger off the trigger until you are on target and ready to fire;
identify your target and what is beyond it
B. Keep the weapon unloaded at all times; always wear hearing protection; never fire
without permission; store ammunition separately
C. Treat every firearm as if it is loaded; always use the safety selector; fire only in semi-
automatic mode; keep the weapon holstered when not in use
D. Never point a weapon at a person; always clear the weapon before handling; keep the
bolt to the rear; fire only at approved targets
Correct Answer: A
Rationale: The Four Universal Safety Rules are foundational to all military firearms handling:
(1) Treat every firearm as if it is loaded — this mindset ensures constant vigilance regardless of
assumed condition; (2) Never point the muzzle at anything you are not willing to destroy —
muzzle awareness is the primary mechanical safety; (3) Keep your finger off the trigger until
you are on target and ready to fire — trigger discipline prevents negligent discharges; (4)
Identify your target and what is beyond it — ensuring positive target identification and
awareness of backstop and potential collateral effects. Options B, C, and D include important
practices but do not correctly enumerate the four universal rules as established by DOD
firearms training doctrine.
Q2: During a live-fire range exercise, the Range Safety Officer calls 'Cease fire!'
What is the correct immediate action for an M240 gunner?
A. Continue firing until the current belt is expended, then cease fire
B. Immediately stop firing, place the weapon on safe (if applicable), keep the muzzle
pointed downrange, and await further instructions
C. Unload the weapon immediately and step away from the firing position
