Why are the classic anti-slope fortifications and infantry three-point tactics not common now?

Anti-slope fortifications and three-point tactics were once very popular tactics in our army, which helped our country win many foreign wars. But now this tactic is almost invisible, and the reason why this tactic is not common now is actually very simple. First of all, the establishment of this tactic is based on the actual combat experience during World War II and the Korean War. Now entering the information age, tactical thinking has also changed. Secondly, the infantry three-point tactic is a tactic used by infantry when attacking without the cover of tanks and armored vehicles. Finally, various modes of war have entered a new mode of informationization, and the previous tactics must be innovated.

First of all, the establishment of this tactic is based on the actual combat experience during World War II and the Korean War. Now entering the information age, tactical thinking has also changed. We must know that during the World War II and the Korean War, our army's weapons were not so developed, and there was still a very big gap with the advanced countries led by the United States. Therefore, we should use this tactic to give full play to our strengths and attack the enemy's weaknesses. Even took a large-scale midnight oil and cold shot cold bubble movement.

Secondly, the infantry three-point tactic is a tactic used by infantry when attacking without the cover of tanks and armored vehicles. You know, at that time, our army basically had no advanced weapons, and the tank force was only the World War II tank T-34/85 sold to us by the Soviet Union. Therefore, this requires attacking the enemy only by infantry without the cover of tanks.

Finally, various modes of war have entered a new information mode, so the previous tactics must be innovated. Modern land warfare has entered a new mode. First, our air force seized air superiority and attacked local firepower points. Then, our main battle tank used its own heavy armor and strong guns to cover the rear step chariot and quickly hardened to a position about 400 meters away from the enemy line. At this time, according to the situation, the infantry brothers in the chariot will be put down and occupy the enemy's position.
