Once upon a time, the fighting method was such that a line of soldiers would stand in front of a line of enemy soldiers. The lines of soldiers were no more than 50-80 meters apart - and they would shoot at each other until the soldiers were gone. Such a fighting method required iron discipline in the soldier - because in fact the soldier was placed in front of a firing squad - literally! In order to instill discipline in the soldiers, they would train them in order drills - the purpose of this order drills is to instill the orders into the heads of the soldiers. The soldier would hear and carry out orders automatically even if it was harmful to him. Thus, contrary to human nature, soldiers could stand calmly in a row in front of the shooters who actually killed them from a relatively short range. Since 1914, this method of fighting has passed from the world, therefore drills in the army are only for show and have no military interest. The Israeli army, for example, does not conduct training exercises that are seen as a waste of energy and manpower without a significant contribution to the war effort.
