Why didn't military training shoot?

This year's military training is more formal, just like the assassination training of the army, which is basically a traditional reservation, so live-fire shooting has basically been cancelled. Today's soldiers can't go to the battlefield in military uniforms and guns like World War II. It's no use letting students learn to shoot. It is better to train new recruits specially.

It is also a very important reason that you can't choose a gun now. At that time, China did not ban guns for some time. At that time, the output of rifles was high, and you could easily find Type 56 semi-automatic guns. Now, we can't. It's troublesome to get approval with a gun. You can't take out the retired old guns, and the reliability can't be guaranteed. Who is responsible for the accident?
