Aldnoah.Zero deals with military organization and robot design form/functionality. Also the strategies required to overcome a strong but limited enemy with a weaker but more supplied force.
Knights and Magic goes even deeper with upgrading mecha designs as its core premise. Redesigning, upgrading, adapting and creating new functions and techniques. All to make better robots.
Knight of Sidonia shows the choices required for a small space colony with limited resources to survive a war of attrition. From food management, material gathering and expendability of their own citizens when more valuable resources are at risk.
