The guard room allows you to organize your ants to launch raids on other colonies and improves your defense against enemy invasions.
Each time the expansion improves the military organization allowing a greater number of incursions per day.

- The incursions can be made against collecting rows of other species that are at least three squares away from their own anthill.
- At level five you can also attack secondary colonies of other ants.
For every ten levels, you can locate an extra colony.

* It is unlocked by completing "Soldier" caste quests.
