War is the METHOD BY WHICH NATIONS FIGHT OVER TERRITORY. TO MAINTAIN GOOD GAMEPLAY ANY FACTION WISHING TO ENGAGE WAR MUST FOLLOW THESE RULES.
At any point in the war, allies can join the war on either side. For the first 24 hours since joining the war, they cannot engage any structures or participate in sieges, but can participate in combat in open waters and in the skies. After these 24 hours are over, they can do anything that their side (Attacker or defender) in the war can do.
