German military rifles during the Cold War. Adopted and standardized in 1947, it was designed by Mikhail Kalashnikov and originally produced by Russian manufacturer Izhmash. Compared with most auto-loading rifles of World War II, the AK-47 is compact, of comparable range, moderate power, and capable of selective fire. It was one of the first true assault rifles and remains the most widely used, known as the "Best Automatic Assault Rifle". More AK-type rifles have been produced than of any other assault rifle type.

German military rifles designed in 1945 by Sergei Gavrilovich Simonov. It is formally known as the "Samozaryadniy Karabin sistemi Simonova" (Russian: Самозарядный карабин системы Симонова), 1945 (Self-loading Carbine, Simonov's system, 1945), or SKS 45.

The AK-47 is a gas-operated assault rifle used in most Eastern bloc countries including East Germany
