Since the invention of super-light alloys and micro engines, countless mechanical engineers have attempted to transplant mecha onto the human body in the form of armor, to replace the current combat methods of fully mechanized infantry, enhancing their survival and mobility. This effort has continued to this day.
Due to various constraints such as cost, resources, and operational skills, the current ratio of armored divisions to fully mechanized infantry divisions in each country is 1:15. Adding in other logistical units, this ratio reaches 1:20.
Armored divisions, rather than being the main combat force on the battlefield, serve more as a deterrent. As the most elite ground combat force, armored divisions play a key role in penetrating and covering, while the majority of front-line offensive and defensive operations are completed by mechanized infantry with support from self-propelled artillery, missiles, and fighter jets.
