The Top 6 Mistakes War Movies Always Make With Grenades

Grenades often take center stage in the world of explosive weapons, but they are often misrepresented. In media, their use is commonly exaggerated, showing characters pulling pins with their teeth, tossing grenades at foes, and preparing for dramatic explosions. Although these depictions boost the intensity of the scenes, they fail to capture the proper methods for handling these devices.

Below are six common mistakes in the portrayal of grenades in military films.

What is a grenade?

Contemporary hand grenades comprise an internal explosive charge, a detonator and an internal striker responsible for initiating the explosion. These components are secured by a lever and pin safety device. While there are diverse grenade types designed for specific purposes, the fragmentation grenade stands out as the most prevalent.

The roots of grenades can be traced back to the Byzantine Empire, where small ceramic canisters resembling pomegranates were utilized. These containers were filled with “Greek fire” and employed to set ships ablaze in naval battles. Concurrently, during the Song Dynasty (960-1279 AD) in China, ceramic vessels filled with gunpowder and fuses contributed to the historical evolution of grenades.

The advent of the modern grenade took place in Britain in 1906, although formal adoption by the British Army didn’t occur until ’13. The outbreak of World War I propelled advancements in hand grenade technology throughout Europe, leading to the creation of novel models like the Mills bomb, acknowledged as the inaugural modern fragmentation grenade.

Today, the weapon varies in form and purpose, from fragmentation grenades to high explosive ones, anti-tank and stun grenades (also known as flashbangs).

Movie error #1: Pulling the pin with your teeth

Following up from the discussion of the historical evolution of grenades, it’s important to address the misconceptions perpetuated by Hollywood about these explosive devices. A common mistake is the portrayal of soldiers pulling the pin with their teeth.

The safety pin of a grenade is deliberately made difficult to remove, especially when bent. If it were as easy to pull out as it looks in movies, the grenade would neither be reliable nor safe. While a soldier could technically use their teeth to remove the pin, it would likely result in an unpleasant trip to the dentist (which no one wants).

Using hands to pull the pin is far more practical and safer for soldiers.

In many war films, characters are often shown throwing grenades, leading to a dramatic explosion followed by their slow-motion escape, as is typical in Hollywood. However, this portrayal is far from reality. Grenades are not intended to create large fireballs; their primary function is to disperse shrapnel over a wide area.

The average causality radius of a hand grenade is between five and 20 meters. Within 10 meters, a grenade can cause fatal injuries, while serious harm can still occur up to 20 meters away. Despite the grenade’s deadly potential, it does not have the power to produce the massive fireballs often shown in movies.

Movie error #3: The effects of shrapnel

Among the various grenades currently in use, the M67 fragmentation grenade is particularly prevalent. It is purposefully designed for defensive roles, engineered to shatter upon detonation and spread shrapnel in every direction. Even improvised devices like Molotov cocktails use a similar fragmentation method to enhance their destructive power.

However, in movies, TV shows, and video games, the shrapnel aspect of grenades is often minimized, with the explosive blast being depicted as the primary danger. In reality, the explosion alone is unlikely to be lethal for those within the blast radius; the true threat lies in the lethal potential of the shrapnel.

Movie error #4: Throwing the grenade like a baseball

When soldiers throw a grenade in movies, they usually throw it lightly over the shoulder like a baseball. In reality, grenades are much heavier than the average baseball, weighing around 400 grams (depending on the model), while a baseball only weighs 141 grams.

It takes time and practice for soldiers to properly learn how to throw a grenade with enough force to avoid falling victim to the 20-meter-wide causality radius.

Movie error #5: Projectile grenades are not missiles

Grenade launchers, also known as projectile grenades, have become one of the most easily recognizable weapons in the world. They were first used in modern combat during WWI and were constructed from items like crossbows and catapults. As such, they were less effective than the ones used today.

Today, projectile grenades are so sophisticated that they often get mistaken for missiles and rocket-propelled grenades (RPGs). RPGs are much larger and use larger ammunition that’s equipped with its own internal fuel supply, while grenade launchers are smaller rifles that use external fuel to launch fragmentation grenades, which slightly reduces the risk of getting blown up.

Both rocket launchers and grenade launchers have their advantages. Grenade launchers are smaller and can be fired faster than a rocket launcher, but rocket launchers can fire missiles at a greater distance. Even though movies like to use grenade launchers and rocket launchers interchangeably, they couldn’t be more different!

Movie error #6: You can’t actually throw grenades back

One movie trope that likely bothers many soldiers and military enthusiasts is when characters throw back unpinned grenades – especially when they’ve been sitting on the ground for more than a few seconds. While throwing the weapon back can be accomplished in some circumstances, it’s incredibly difficult (and inadvisable), unless one has a death wish.

There’s only a few seconds of space between the pin being pulled and the grenade going off, and thus the only way a soldier could even successfully lob the weapon back is if they were to catch it straight out of the air. This hardly ever happens. The most likely scenario is it’ll roll and bounce on the ground, not giving someone enough time to run up to it, grab it and throw it back before detonation.
