The saying goes, "the shorter the weapon, the greater the danger," and ancient assassins most commonly used stabbing techniques, even naming them after such moves.
In close combat, the effect of stabbing or thrusting is far greater than that of slashing or chopping, which might look fierce.
And indeed, "the longer, the stronger." Among ancient military units, Spearmen were the most famous and practical.
With just a little training and learning a stabbing technique, Spearmen could go to battle. By using their length and the advantage of group fighting, enemies with swords and other weapons couldn't even get close, and a chaotic barrage of spears would turn them into a hornet's nest.
Therefore, aside from specialized troops like archers, shield-sword soldiers, and Cavalry, the stab of a Spearman was the main melody of melee combat on the Cold Weapons battlefield.
