You probably mean the AK-47. But the Ak-47 was not a sub-machine gun, it is an assault rifle. SMG's shoot pistol rounds such as 9x19mm Luger. Assault rifles fire scaled down versions of full power rifle rounds. The AK-47 for example shoots 7.62x39mm which is a scaled down version of the Russian 7.62x54mm rifle round used in the Mosin Nagant rifle.
cant be compared! UMP is a sub machine-gun and AK-47 is an assault rifle! different characteristics and different uses they have!
The AK-47 assault rifle was made in the Soviet Union. It was designed by Kalashnikov. It has features taken from a variety of different rifles. He was lying in a hospital bed during World War 2. His rifle had jammed. He dreamed of a rifle that could get muddy and would still fire. He created such a rifle.
The first "assault rifle" (meaning, a small, lightweight, fully-automatic rifle firing relatively small ammunition, suitable for light infantry and paratroops) was developed by Germany. The design was adapted by the Soviets to develop the Automat Kalashnikov model 47, or "AK-47".
