Just like small kingdoms ruled by players we also need alliance kingdom because that would be nice to have.
Walls : prevent enemy troops from passing, weak against enemy siege units
Watch towers : can be used to execute enemy troops attacking nearby alliance structures or those who come on its range also weak against siege units and can also be used as strongholds with around 50k men
Territory flags : this one is the same as the normal flag but can be only in small quantities only to prevent others from teleporting inside of the chosen territory by the leader.
Gates : allows allied troops to come and go, with less durability than walls, and can also be used like level 1 pass and as a stronghold.
