There are multiple ways to increase your stats and limits in Battlecry, allowing you to become stronger and more efficient.
You can use Skill Points in the R&D section to increase your maximum Health, Ammo, and Supplies. Skill points can also be used to boost your attack and defense power.
Tactic Points, earned through gameplay, can be assigned to Ground, Air, or Naval categories to improve your military strength in those areas.
Your level also plays a major role, as many limits, like the number of commanders in battle or captains you can use, scale with your level.
Additionally, Special Operations can reward you with permanent boosts that further improve your stats and capabilities.
