Battlecry allows you to choose a strategy that affects how your resources are generated.
There are three options available:
Ammo Strategy increases the rate at which your ammo regenerates.
Supplies Strategy increases how quickly your supplies recover.
Cash Strategy boosts your income generation.
You can switch between strategies, but it requires spending Gold Bars.
Choosing the right strategy depends on your playstyle. If you battle often, Ammo may be more useful. If you focus on Operations, Supplies can help. For long-term growth, Cash strategy is a strong option.
