The domestic LG-5 40mm sniper grenade launcher was unveiled at China International Police Equipment Expo, attracting countless eyes. This "big guy", known as the "sniper gun", has great power, domineering appearance, high precision and good portability.

Some people call LG-5 a "new and new human" in the family of Grenade launchers. Because it is so mixed and fashionable, it is very different from the original Grenade launcher in both form and function.

When the hand turned back to the beginning of the 20th century, as early as the First World War, the prototype of Grenade launcher appeared-Grenade launcher.

In the heavy artillery fire of World War II, infantry often struggled: what should be used to attack small targets? Grenade has poor accuracy and insufficient power, while mortar has effectively improved accuracy, but its power is too high, which not only wastes ammunition, but also is easy to be accidentally injured.

The Germans began to try to add a folding butt to the 27 mm signal gun and fire a small fixed Grenade at the shoulder. Since then, the traditional Grenade launcher has officially entered the battlefield.

Americans contributed to the "American Plan" by solving difficult problems: 1953, Springfield Arsenal developed the M79 40mm Grenade launcher. It looks like a rifle, also known as a "grenade gun". Seven years later, with the approval of the US War Department, the "Grenade Gun" was officially installed in the army and became the "old squad leader" of the Grenade launcher family. Since then, Grenade launchers have embarked on the fast track of professional development.

With the end of the cold war, Grenade launchers are no longer a single "rifle" form. Some can launch grenades independently, some appear as accessories of firearms, and some need to be erected before launching. The MM- 1 Grenade launcher developed and produced by Hawke Engineering Company of the United States is one of them. Its range is similar to that of submachine gun, and its operation is flexible, so it is a sharp weapon for urban anti-terrorism.

In addition, the US military also put two types of grenade machine guns into the Gulf War. 1600 Iraqi soldiers were captured in one battle. About one sixth of them were injured by Grenade fragments fired by MK 19 Grenade machine gun. The birth of grenade machine gun greatly made up for the shortcomings of complicated loading procedure and poor hitting accuracy of grenade launcher.

With the development of science and technology, the importance of air and sea battlefields has become increasingly prominent. Grenade launchers have started the "slimming" mode, and the design of heavy machine guns has turned to the direction of reducing weight, improving power and streamlining matching.

A typical example is the AGL40 Grenade launcher. Its "battle position" is almost everywhere and can be launched on trucks, armored vehicles, helicopters and even patrol boats.

From "rifle" to "giant pistol" and then to "slender machine gun", reviewing the evolutionary history of Grenade launchers, two words can be accurately summarized: fickle. With the continuous growth of new technology, the family constantly explores new battlefields with its 72 skills.

At the China Air Show, the LG-6 Grenade launcher developed by China was unveiled. Light weight, strong function, can be used for mobile operations in mountainous areas and jungles, and can also be used for urban street fighting and anti-terrorism and riot prevention tasks. The shoulders of individual soldiers are its powerful "backing", and drones can also be its excellent "mounts".
