A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces. Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle.
The AK-47 rifle, on the other hand, is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. Even though it’s commonly associated with their Soviet Union creators, it has been manufactured in many countries and has seen service with armed forces as well as irregular forces worldwide, and was the basis for developing many other types of individual and crew-served firearms.
In this video, Steve & Marchy get the opportunity to shoot a rather large (fake) rabbit using full auto AK47’s and the LG4-40mm Grenade launcher. It’s an interesting choice of military infantry weapon for this task, which makes it fascinating to watch. Check it out:
