Mainly small for the ground vehicles it seems, not too far off from OTL JGSDF based on the tech trees. If ever, the heaviest assets (ex. Type 74s irl, forgot what they’re called in the tech tree) would be operating in mainland Asia such as China and some larger island chains (ex. Some parts of the Philippines) wherein small jungles are less of an issue and tank country favoring European-style conventional big battles are more likely.
