The Army Infantry, which occupies a very unique position among the many mercenaries, has the strongest attack power in the gun line through its powerful machine gun launch, serving as the best damage dealer in the gun line with Fire Mage, while quickly building up military artillery to protect allies from enemy shooting, and also using grenades to cause splash damage to a certain range of enemies. They even use a powerful whistle & instructor force to train their opponents in a standard way, and they catch a military flag so closely that they sometimes go to a cliff.
