Description
An Assault Rifle is a selective-fire firearm using a projectile with muzzle energies in between those of a full sized rifle and a pistol. Assault rifles are categorized in between light machine guns, intended more for sustained automatic fire in a support role, and submachine guns, which fire a pistol cartridge rather than a rifle cartridge.The MA2B Assault Rifle is a reliable and accurate weapon. The "Assault Rifle" can shoot 7.62mm of armor piercing rounds making it a useful weapon.

History
Assault Rifles date back to the end of the Second World War. Germany made the first assault rifle, called the Sturmgewehr 44, in 1944, to help turn the tide of the war. Then came the Russian AK-47, which basically set the definition of assault rifle. By the time of the Halo trilogy, most assault rifles also house an onboard electronics suite, showing ammo capacity, a compass and other information without the use of a HUD.
