During World War II, the Soviet supply was very interesting and divided into two lines.
Each line is an area not occupied by the Nazis. At that time, it was compulsory military service, and the age of enlistment was lowered again and again. In 43 years, due to the serious fatigue of soldiers, the minimum age was lowered to 16, and the maximum age was put to 50.
The second line is the Nazi-occupied area. With the great counterattack, the Soviet Union liberated these areas. According to the memoirs of the generals, after the liberation of these areas, the shovel office was responsible for screening out people who had cooperated with the Germans.
Other men, as long as they meet the requirements, put on military uniforms and join the army after eating.
Many people lack basic training and die as soon as they go to war.
