Почему во время ВОВ существовали десятки видов патронов?

During World War II, soldiers used more than just one type of ammunition. In addition to standard ammunition, there were armor-piercing, tracer, incendiary, armor-piercing incendiary, and many other types.

In this episode, we'll take a detailed look at the types of ammunition used during the Great Patriotic War, how they differed from each other, where they were used, and what myths about them persist to this day.
