It's real bullets, that is, live ammunition used in war, not so-called empty bullets. I learned it from the "hunter" special forces school in Venezuela, which put psychological pressure on the special forces. So is the so-called "death index" of special forces. If there are major or extraordinarily serious training casualties in other troops, the head of the army will be demoted or even court-martialed, but it is nothing to kill a few people in the special forces every year. This is the death index, because it is cruel. In order to arouse the enthusiasm and mobilize outstanding non-commissioned officers to join the special forces, the army leaders even promised that all the top scouts who participated in the assessment and training of the special forces would be awarded third-class merits. Anyone who has been a soldier knows what third-class merit means: you only earn third-class merit in one life! The cruelty of special forces training can be seen! Live ammunition training is almost the common practice of the world's top special forces.
