FMF - Fleet Marine Force Infantry Weapons Fundamentals Questions and Answers 1

Question 1

Which of the following BEST describes the primary role of the M27 Infantry Automatic Rifle (IAR) within a Marine Corps fire team?

Accepted Answer

To provide accurate, suppressive fire while maintaining maneuverability with the fire team.

Answer

The M27 IAR was adopted to provide accurate suppressive fire, an approach thought to be more effective than the high volume of less-accurate fire from the M249 SAW. Its lighter weight and similarities to the M4 carbine allow the automatic rifleman to keep pace with the rest of the fire team.

Question 2

A Marine is firing an M240B machine gun. The gun fires a long burst and then stops. The barrel is glowing red and emitting heat waves. What is the MOST critical immediate action the Marine should take?

Accepted Answer

Wait approximately 15 minutes, keep the weapon pointed downrange, and then conduct a barrel change.

Answer

A barrel that is glowing red indicates it is extremely hot (a 'hot barrel'). A hot barrel can cause a round to 'cook off,' meaning it fires without the trigger being pulled. The proper procedure is to wait for it to cool for a safe period, keeping it oriented in a safe direction, before attempting to change the barrel or clear the weapon.

Question 3

What are the four universal firearm safety rules that are fundamental to all Marine Corps weapons handling?

Accepted Answer

1. Treat every weapon as if it were loaded. 2. Never point a weapon at anything you do not intend to shoot. 3. Keep your finger straight and off the trigger until you are ready to fire. 4. Keep the weapon on safe until you are ready to fire.

Answer

The four universal firearm safety rules are: 1. Treat every weapon as if it were loaded. 2. Never point a weapon at anything you do not intend to shoot. 3. Keep your finger straight and off the trigger until you are ready to fire. 4. Keep the weapon on safe until you are ready to fire. These rules are foundational to all weapons training and handling in the Marine Corps.

Question 4

During a live-fire range, a Marine's M4 Carbine fails to fire. The bolt is forward, and the ejection port cover is closed. According to the immediate action drill, what is the first step the Marine should take?

Accepted Answer

Slap upwards on the bottom of the magazine.

Answer

The immediate action drill for a stoppage with the bolt forward is often remembered by the acronym 'TAP, RACK, BANG'. The first step, 'TAP,' involves slapping upward on the magazine to ensure it is properly seated, as a poorly seated magazine is a common cause of failure to feed.

Question 5

Which characteristic correctly describes the M240B medium machine gun?

Accepted Answer

Gas-operated, air-cooled, and belt-fed.

Answer

The M240B is a belt-fed, air-cooled, gas-operated, fully automatic machine gun that fires from the open-bolt position. It is chambered in 7.62x51mm NATO.
