Old A's life is similar to the real life of special forces in reality. But what is certain is that from all kinds of information, training is more difficult, subjects are more complicated and tasks are more arduous. Even "inhuman." As for the details, I suggest you take a look at the training in Rushing out of Amazon and Shiwei Island to understand the hardships. Of course, some high-tech operational details may not be available.

As a killer weapon in the military combat troops, it also serves as the task of simulating foreign military operations. Clothing, food, shelter, transportation, combat weapons, training methods and tactics are different from those of traditional troops. Some are completely similar to foreign troops except people. Even soldiers eat with knives and forks, and some slogans are all in foreign languages.

Judging from the play, Old A's life, equipment and tactics should be imitated by foreign troops. In training, they carry logs, attach importance to team fighting, and are good at sniper fighting. Not only are there professional snipers like Cai Cheng, but almost every member is a good shooter.

In the last few episodes, the armored reconnaissance battalion of Gao Cheng's division used the imitation of 16A2, and the military uniform was also specially made, indicating that the PLA is paying more and more attention to the study of foreign troops, expanding the troops that simulate foreign military operations, and letting more conventional troops know each other and know each other, so as to be invincible.
