How much influence did tactics/strategies have on the war?

 Most of the haters often weigh their military strength by the amount of military training and military discipline.However, the most important things in war are tactics and strategies.Among them, there are many people who overlook organization, command, and military discipline. The biggest reason why Rome became a power was its flexibility.We used to change weapons, tactics and organization as needed.Rome took advantage of the characteristics of the battlefield and their strengths very well.In order to break down the initial dense formation and launch a siege, the forces were divided into medium-sized groups and the resulting command and discipline system was established.After that, when a dense formation was needed, the organization was revised and divided into a larger scale.Since then, as defensive strategies are needed and military discipline and loyalty gradually decrease, they hire mercenaries, build generals, and turn to conciliate the enemy. On the other hand, Roman enemies were not.The Gauls, who were used to local warfare and difficulties rather than competition using dense formation, were of course no match for the competition.Similarly, Persia, accustomed to battles through bravery and powerful equipment, did not show much power in a head-on confrontation with Rome, armed with unity and strength. Another example is Mongolia.Mongolia has the best organization and combination for rotation.However, as the battlefield changed and the siege was mainly carried out, changes were made, such as putting the indigenous people on the floor and incorporating engineers.It continues to show strong power.The Franks also fought a charge and a turbulent battle, and they won the battle with heavy-armed infantry against powerful cavalry such as Sogoth and Saracen. The same was true of the Korean dynasties.Based on the characteristics of the terrain, tactics and strategies suitable for Mercury warfare rather than rotation were developed, the fortress was remodeled to be suitable for defense, and the soldiers were fostered to hit the rear while the fortress was defending, and the bow needed for the sit-in was focused.However, Tangeumdae Terrace and Geunwanggun Battle went on a head-to-head turn with troops and generals familiar with tactics and strategies suitable for Suseong War, and the result was a disastrous defeat. Putting these aspects together, the most important thing in tactics and strategies is also Zippigi.If you know whether the enemy is strong in rotation, in sit-in, in dense formation, in battle, in maneuver, or in defense, and know what kind of battle our troops are capable of, you will be able to defeat them with a great deal of confusion.
