A Comprehensive Guide to Military Grenades: Types and Uses

Grenades are essential tools in the arsenal of any modern military force, offering versatility in close-quarters combat. The United States Army, for example, utilizes a variety of grenades, including High Explosive (HE) types, flashbangs, and smoke grenades. This comprehensive guide delves into the different types of grenades used by the US Army and other armies around the world, their functionalities, and their deployment.

What Are Grenades?

Grenades are expendable, portable, hand-thrown or remotely detonated, explosive weapons used in close-quarters combat for various purposes, including providing cover, disabling or destroying targets, and sometimes used to create distractions. They range from the simple to the highly advanced, depending on their intended use and the needs of the specific military force.

Common Types of Grenades Used by the US Army

High Explosive (HE) Grenades

The High Explosive (HE) M67 hand grenade is one of the most commonly used grenades by the US Army. It is designed to be thrown at a target to deliver a blast effect. The shell casing of the grenade consists of a ring of steel wires, which, upon detonation, produces a concussive force that can cause physical damage to personnel within the blast radius. HE grenades are effective for breaching walls, destroying light fortifications, and other tactical purposes.

Flashbang Grenades (SME)

A Flashbang, also known as a stun grenade (or less commonly, CLAT) or SSM-1, is a non-lethal anti-personnel weapon used for disorienting or temporarily incapacitating targets. The Flashbang grenade is composed of an aluminum shell filled with an explosive charge, and when ignited, the grenade emits a loud, blinding flash of light and a high-pitched sound wave designed to temporarily disorient the occupants of a room or area. Flashbangs are commonly used to provide cover for tactical operations, such as raids or breaching fire curtain doors. They can also be used in certain scenarios to clear a room or incapacitate individuals without lethal force.

Smoke Grenades (610)

A smoke grenade, specifically the US Army's M610 90M visibility smoke grenade, is designed to produce a cloud of smoke that can conceal or obscure the battlefield. When ignition occurs, it releases an aerosol mist of smoke that provides a breathable, low-visibility environment, especially useful in reconnaissance and disengagement operations. Smoke grenades are often used to provide cover during movement, assist in maintaining radio communication, or disrupt enemy observation and fire.

Other Types and Uses of Grenades in Military Applications

Beyond the common types used by the US Army, many other armies around the world deploy a wide range of grenades for various missions:

Fragmentation Grenades

Fragmentation grenades, like the M76, are designed to disperse fragments over a larger area, making them effective against soft targets and armor. They are often used in permissive environment operations where booby traps and improvised explosive devices (IEDs) may be weapons of choice by the enemy.

Inch Grenades

Also known as palm grenades or a hand grenade. Inch grenades are designed to be thrown or pulled, and when they reach their apex, they explode, dispersing shrapnel. These are often used in close quarters combat, in areas where the user is in close range of the target.

Thermal Grenades

Thermal grenades, such as the US M67A1, are designed to ignite a flammable material to release a self-sustaining flame, used to destroy enemy installations, equipment, or other structures that can be ignited. They are less commonly used today as more advanced non-lethal alternatives are available.

Conclusion

Understanding the different types of grenades and their uses is crucial for any military force, especially for the US Army, which must remain adaptable and efficient in a constantly evolving combat environment. By choosing the appropriate grenade for the mission, whether it be high explosive, flashbang, or smoke, soldiers can effectively carry out their missions, ensuring the safety and success of their operations.
