How can I get reinforcements if I’m under attack?
If your Base is under attack, all your units in the Barracks, Garage, War Factory will engage in combat against the attacker. If you find yourself being under attack and you think the Army in your Base are not enough to defend yourself, you can ask other Players in your Guild, via the Guild Chat, for help to send units or an Army to Reinforce your Base.
To Reinforce a friendly Base, just tap the Base and choose "Reinforce". You are then directed to form a Squad that will be sent to reinforce that Base. Once the Squad arrives, they will stay defending that Base until you withdraw by tapping the Base and choosing "Call back". In battle, the reinforcing Squad will fight together with the Units in training against any attacking Army
