A Kalashnikov rifle is any one of a series of automatic rifles based on the original design of Mikhail Kalashnikov.
 They are officially known in Russian as "Avtomat Kalashnikova" ("Kalashnikov's Automatic Gun"; Russian: Автома́т Кала́шникова ), but are widely known as Kalashnikovs, AKs, or in Russian slang, as a "Kalash".
 They were originally manufactured in the Soviet Union, primarily by Izhmash, but these rifles and their variants are now manufactured in many other countries.
The 56th Rifle Division was a infantry division of the Red Army of the Soviet Union.
 On 21 November 1919 the 56th Rifle Division () was established from a previous rifle division that had been part of the Seventh Red Army.
 In June 1941 it was part of the 4th Rifle Corps of the 3rd Army (Soviet Union).
 Its first formation was destroyed while serving with 4th Rifle Corps by July 1941.
The TKB-408 was an early gas-operated prototype bullpup assault rifle with a tilting bolt.
 It was created by German A. Korobov and submitted to a set of official trials conducted in 1946 to select an assault rifle for the Red Army.
 None of the designs submitted to these trials were selected, although the AK-47 that was later adopted was a heavily modified variant of Mikhail Kalashnikov's AK-46.
The Kalashnikov AK-12 is a Russian 5.45×39mm assault rifle, designed and manufactured by Kalashnikov Concern (formerly Izhmash).
 It is the newest derivative of the Russian AK-Pattern series of assault rifles and was proposed for possible general issue to the Russian Army.
 The rifle is intended to eventually replace previous generations of Kalashnikov 5.45×39mm assault rifles in service with the Russian military and other governmental forces.
 The rifle has two main variants, the AK-12 chambered in 5.45×39mm cartridge and the AK-15 chambered in 7.62×39mm cartridge.
The RPK ("Ruchnoy Pulemyot Kalashnikova", Russian: "Ручной пулемёт Калашникова" or "Kalashnikov hand-held machine gun") is a 7.62×39mm light machine gun of Soviet design, developed by Mikhail Kalashnikov in the late 1950s, parallel with the AKM assault rifle.
 It was created as part of a program designed to standardize the small arms inventory of the Red Army, where it replaced the 7.62×39mm RPD light machine gun.
 The RPK continues to be used by the armed forces of countries of the former Soviet Union and certain African and Asian nations.
 The RPK was also manufactured in Bulgaria and Romania.
The Saiga-12 ( ) is a 12-gauge shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named for the Saiga antelope.
 Like the Kalashnikov rifle variants, it is a rotating bolt, gas-operated gun that feeds from a box magazine.
 All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly.
Pyotr Filippovich Berestov (Russian: Пётр Филиппович Берестов ; December 21 [O.S. December 8] 1896 , Berestovo – November 26, 1961, Zaporozhye) was a Red Army major general during the Second World War.
 Drafted into the Imperial Russian Army in 1917, Berestov participated in the Russian Revolution.

 He became a Red Army officer and served in several positions during the interwar period.
 Berestov was arrested and released during the Great Purge.
 He fought in the Winter War as a regimental commander.
 In the early days after the German invasion of the Soviet Union, he was given command of a People's Militia regiment, which was converted into a regular regiment.

 Berestov became the division's commander and in the spring of 1942 briefly led the 50th Rifle Division.
 In April, he took command of the 331st Rifle Division, which he led during the rest of the war.
 For his leadership, Berestov was awarded the title Hero of the Soviet Union in late June 1945.
 Postwar he commanded the 72nd Guards Rifle Division, which was downsized into a brigade, and the 43rd Guards Rifle Brigade, which became the 113th Guards Rifle Division.
 Berestov retired in 1955 and lived in Zaporozhye until his death in 1961.
The Vepr-12 is a multipurpose semi-automatic detachable-magazine shotgun, produced by Molot-Oruzhie Ltd.
 It is patterned after the original Kalashnikov rifle and built on the heavier RPK light machine gun receiver.
