If the opponent's units are completely stationary and within range, it is impossible to swing more output than not to swing, and often a lot of output will be lost because of imperfect operation.

But usually in a battle, the other side will move, either rushing to you or running away. The reason for throwing away the gunman is to be able to move at the same time without losing too much output. Any unit's attack has attack intervals. It moves immediately after the first attack, ending the attack interval, and stops moving when the second attack is to be carried out, so that the movement is completed by using the attack interval, and the pause is the attack time. The closer the pause interval is to the attack speed interval, the smaller the attack output loss will be. When you throw it forward, you can hit it a few more times before the opponent escapes from the attack range. Swing backwards to attack at the same time, as far away from the opponent's melee units as possible.
