Assault rifle From Wikipedia, the free encyclopedia For the United States legal and political term, see assault weapon. The StG 44, the first true assault rifle, was adopted by the Wehrmacht in 1944. It fires the 7.92×33mm Kurz round. Currently the most used assault rifle in the world, the AK-47 was first adopted in 1949 by the Soviet Army. It fires the 7.62×39mm M43 round. The M16 was first introduced into service in 1964 with the United States Air Force. It fires the high velocity 5.56×45mm NATO cartridge and is the second most used assault rifle in the world after the AK-47. An assault rifle is a selective fire (selective between automatic, semi-automatic, and burst fire) rifle that uses an intermediate cartridge and a detachable magazine.[1] Assault rifles are the standard service rifles in most modern armies. Note the difference between the assault rifle and the battle rifle. Assault rifles use smaller cartridges and are used at closer ranges than battle rifles. The larger sized rifle cartridges used in battle rifles make fully automatic fire more difficult. Fully automatic fire refers to an ability for a rifle to fire continuously while the trigger is pressed; "burst-capable" fire refers to an ability of a rifle to fire a small yet fixed multiple number of rounds with but one press of the trigger; in contrast, semi-automatic refers to an ability to fire one round per press of a trigger. The presence of selective fire modes on assault rifles permits more efficient use of rounds to be fired for specific needs, versus having a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness. Examples of assault rifles include the StG 44, AK-47,[2] M16 rifle, QBZ-95, FAMAS, Heckler & Koch G36, and Enfield SA80. The assault rifle became the standard military rifle during the Vietnam War.[3] The Soviet Union was the first nation in the post-war era to adopt an assault rifle, the AK-47, and other nations followed later. Combat experience during the World Wars had shown that most infantry combat took place at 200–300 meters (220–330 yards) distance and that the winner of any given firefight would most likely be the one with the highest rate of fire. The rifle cartridges of the day were therefore unnecessarily powerful, producing recoil and report in exchange for marginal benefit. The lower power of the intermediate cartridge meant that each soldier could fire more bullets faster and/or with less recoil and its lighter weight allowed more ammunition to be carried. en.wikipedia.org/wiki/Assault_rifle
