After watching the soldiers' assault, I have some questions about the exercise.

First of all, answer your question about cannons.

At present, the artillery firepower is induced by laser, and the central processor judges the casualties of the other side according to the information from the artillery, including the loss or serious injury of armored vehicles.

The current exercises, whether firearms or artillery, include aircraft missiles and so on. It has been informatized and calculated according to the judgment of the military system (director department).

The previous exercises were very rustic, like blank ammunition and colorful bullets, but that was an old calendar, and now I still have a smoke can.

You said that the cannon vibrates, even fragments kill and so on. All of them are calculated by computer, which means that if you happen to be on the edge of a shelling area, your sensor will emit different colors of smoke because of your influence.

Tell you one more thing, the combat system inside the army is much cooler than the games in the world now, and it is particularly substantial, because in wartime, your fingers are tens of millions of lives.
