Is the so-called traditional martial arts useful in ancient battlefields?

Battlefield and martial arts are completely unrelated systems, let alone martial arts. Free fighting in the ancient battlefield also led to death, but it lived longer than martial arts.

First of all, regardless of the ancient and modern wars, no one returned empty-handed, so the battlefields such as fists and fists are nonsense.

Secondly, do the trench, siege soldiers, engineers and cavalry of the military division use martial arts? Archers volley, and there is little chance to aim directly. They pay attention to discipline. It is basically impossible for a rifleman to fight alone and form an array. Relying on coordination and discipline, the movements are basically stabbing and closing guns, because there are few horizontal guns in dense formations. Once the formation is dissolved, the riflemen will die miserably. Different from the rifleman, the sword and shield soldier can engage in close combat, and he is most likely to use some martial arts, but his movements are very simple, such as cutting, stabbing, blocking and falling, and he gets up. When he comes down, either the other person dies or he dies himself. Tell me which faction this is.

Third, when can the earliest martial arts schools be traced back? Did you have it in Shang Dynasty? Without martial arts, the Xia Dynasty would have perished long ago. Did you win the guessing game?

Fourth, Wushu refers to a routine system with strict portal and inheritance, which cannot cover all fights. Wushu and military array are two systems that have existed for a long time and are independent from each other but occasionally learn from each other. Martial arts circles always indulge themselves with the battlefield, and military fans don't care at all. This concept must be made clear. Riding a ladder to fight on the battlefield and hooligans fighting on tables, chairs and benches are not martial arts. Don't post everything. Am I calling martial arts when I let the dog bite? Which school is the Type 95 assault rifle from?
