Posters on small arms
Small arms - barrel weapons for firing bullets or other striking elements. Depending on the source of energy for throwing a striking element, there are fire, pneumatic, mechanical and electric small arms. GOST 28653—90 defines small arms as a barrel weapon with a caliber of less than 20 mm, intended for throwing a bullet, a shot or a canister.
Firearms - a kinetic weapon, in which the acceleration and ejection of the projectile (mines, bullets) from the barrel uses the pressure force of gases produced during the combustion of propellant (powder) or special combustible mixtures. Combines the means of direct destruction (artillery shell, mine, bullet) and the means of throwing them to the target (gun, mortar, machine gun, etc.). It is subdivided into artillery, small arms and grenade launchers.
