Airsoft is the new type of modern games for people love the military things.

The term Airsoft Guns was established in Japan during the early 1980s. It is used to describe a non-lethal realistic replica sized either normal or mini of a real firearm. The gun shoots round 6 mm or 8 mm plastic pellets, which are offered in numerous different weights ranging from 0.12 to 0.88 grams. The most frequent weight is 0.2 and 0.25 grams because of the excellent combination of accuracy and range. Airsoft players use this gun for military or law enforcement recreation scrimmage games. Most popular real firearm has an airsoft gun model.

Airsoft is a game in which participants eliminate opponents by hitting each other with spherical non-metallic pellets fired from a compressed-air gun (or airsoft gun) powered by gas,compressed air, manual spring-load, or electrically powered gearbox.

Airsoft participants organize meetings at dedicated airsoft battlefields often adapted to provide walls, bunkers, trenches, buildings, towers, and other similar man-made field enhancements to offer realism analogous to real war environments.

Airsoft games vary greatly in style and composition depending on location, budget, and quantity of participants but often range from short-term skirmishes, organized scenarios, military simulations, or historical reenactments.

Combat situations on the battlefield often involve the use of common military tactics to achieve the objectives set in each game. Participants typically use varying types of non-lethal weaponry designed as replicas of real firearms, tactical gear, and accessories used by modern military and police organizations.
