I like the addition of these two accessories for unit design. However, I feel they are implemented way too late in the tech trees. By the time you can add them to your units, you already have decent units to build, along with fort bonus and gear, your troops are already pretty tough. However, early game, these two items could spell the difference of defeat and victory. I ask that you move them up to the very first tech trees. For example, First Aid Kits could be learned under Training instead of War Colleges, and Rations could be learned under Restoration instead of Craftsmanship. Please consider this option.
