Posters on small arms
Small arms are barrel weapons for firing bullets or other striking elements. Depending on the source of energy, a firearm, pneumatic, mechanical and electric small arms are distinguished for throwing the injuring element. GOST 28653-90 defines small arms as a barrel with a caliber of less than 20 mm, intended for throwing bullets, shot or grains.
Firearms are kinetic weapons in which the force of pressure of gases generated by the combustion of propellant (propellant) or special combustible mixtures is used to accelerate and eject a projectile (mines, bullets) from the barrel bore. It combines a means of direct destruction (an artillery shell, a mine, a bullet) and a means of throwing them toward the target (cannon, mortar, machine gun, etc.). It is subdivided into artillery, small arms and grenade launchers.
