The first weapons safety rule is to treat every weapon as if it were loaded.

This safety rule was created to ensure that Marines stay alert while handling weapon systems.

When Marines are careless, mishaps may happen, and they could lead to death or injury.

Weapons may not have been cleared properly and still have a live round in the chamber.

By treating every weapon as if it were loaded, Marines can avoid negligent discharges and keep those around them safe.

Weapons must always be checked to see if it is loaded every single time it changes hands.

It is a Marine’s responsibility to ensure that it is unloaded and clear.

They will not accept verbal confirmation on the state of a weapon without physically verifying it themselves.

To properly pass a weapon, a Marine will clear it, look in the chamber, verbally state clear, and the other Marine will do the same after they take control of the weapon.

#2. Never Point a Weapon at Anything You Do Not Intend to Shoot

The second weapons safety rule is to never point a weapon at anything you do not intend to shoot.

If your weapon is loaded or has no rounds in the chamber, the second safety rule applies.

This safety rule is about muzzle awareness, and when it is kept, even if there is a negligent discharge, no one will be harmed.

Much like the first safety rule, it is about keeping the Marine responsible and vigilant to ensure that they are as safe as possible.

This safety rule especially applies to when a Marine is in condition one (bolt forward and round in the chamber) while on the range or in a combat scenario.

There are training events that will require Marines will point their weapons at training combatants.

Some exercises will have Marines use simulation rounds which are like 5.62mm paintball rounds.

Simulation rounds are still projectiles and can still injure a person if misused due to their velocity.

Other events use blank rounds where an adapter is placed in the barrel to prevent projectiles.

During these training events, weapons are cleared before use and afterward to ensure the weapon is clear.

In a combat environment, a Marine will ensure that they have positive identification of their target before engaging as part of their rules of engagement.

Marines are constantly moving through obstacles, conducting drills, or moving to an objective.

It could be easy to accidentally hit the safety of a weapon and set it on fire.

A negligent discharge may occur if a Marine accidentally pulls the trigger while a weapon is unknowingly on fire.

By having your trigger finger extended on the slide or frame, you are ensuring weapon disciple.

#4. Keep the Weapon on Safe Until You Intend to Fire

The fourth weapons safety rule is to keep the weapon on safe until you intend to fire.

Depending on the weapon system that is being used, the safety will be different.

For example, on an M16A4 or M4A1, the safety switch can be quickly accessed by a right-handed shooter’s right thumb, but for an M249 squad automatic weapon, it has a push safety.

It is essential to know where the safety is located on any weapon system used for maximum safety.

Some weapons have multiple safeties that need to be engaged to fire the weapon.

This is the case for pistols like the Springfield XD9, where the pistol has a safety lever, a grip safety, and a trigger safety.

If one of the three safeties is not engaged, the pistol will not fire.

If all else fails, if the safety is on, there is no chance for a mishap.
