First of all, Germany equipped MP- 18 submachine guns and assembled a large number of experienced soldiers during World War I, and then uniformly distributed MP- 18 submachine guns and a large number of grenades to form storm commandos to carry out a large number of trench operations. In battle, storm commandos often use submachine guns and grenades to break into enemy trenches and fight with enemy soldiers armed with rifles at close range, relying on fierce firepower. Often the enemy who is beaten has no strength to fight back. During World War II, the MP38/40 submachine gun equipped by the German army was even more brilliant. Although the firing rate is not as fast as Bobo Sand and the bomb load is not as high as Bobo Sand, it is lighter and more stable. Moreover, the early German armored forces only had light tanks. In the face of guerrillas armed with cluster grenades and incendiary bottles, MP38/40 has well protected the fragile light tanks.
Followed by the Soviet Union, the Soviet Union is also a big country that uses submachine guns. The bomb load of the Soviet Bobosha submachine gun is very large, 7 1 round. Secondly, the Bobosha submachine gun fires very fast. Therefore, in the street fighting in Stalingrad, the enemy is often caught off guard. In fact, the Soviet Union developed the Bobosha submachine gun because it was frightened by the Finnish Somi submachine gun in the Sufen War. Many Finnish guerrillas used somi submachine guns to attack the Soviet headquarters, causing a large number of Soviet casualties. In a rage, the Soviet army studied the captured somi submachine gun. Finally, I took out a mature version of Somy submachine gun, Bobosha submachine gun. In fact, the most important feature of Bobosha submachine gun compared with Somi submachine gun is not that Bobosha submachine gun has one more bullet. But in the case of similar performance, Bobosha is easier to produce. The reliability is higher.
Finally, there are American submachine guns, which are mainly divided into two types, one is Thomson submachine gun and the other is M3 grease gun. Although the industrial capacity of the United States is very strong, it is difficult to manufacture Thomson submachine guns quickly. However, it is still possible to make submachine guns enough for the troops on time and point by point. But this kind of gun is more expensive after all, and although its performance is good, the US military still hopes to get a submachine gun that is very easy to produce. Finally, M3 was born. It was called the grease gun, because the tools used to butter machines in the United States were very similar to M3 without handles and magazines. That's why they are nicknamed grease guns by American soldiers.
Of course, during World War II, Britain was also equipped with a large number of Stern submachine guns. This kind of weapon, which has to be produced under the condition of approaching war clouds, has good performance. And it is worth mentioning that Britain has also developed the world's first submachine gun with silencer. Used to assign special forces to perform tasks behind enemy lines. This special force is called Team L, which is the predecessor of the famous SAS.
