You may attack Enemy Colony using your warrior ants in inventory.

Do the attack

You are in range of an Enemy Colony
Click the colony and select "Attack".
This does one "round" of the attack. I.e. casualties on both sides.
If you have more warriors keep clicking the colony and Attack if you want to attack more.

Defence

The defence is better if there are many Warrior ants. (Can be changed by owner from a distance)

Several people may attack the same colony at the same time.

When you attack you expose your own position to everyone for 5 minutes(?) after the last attack command.

You are in range of an Enemy Colony
Click the colony and select "Start Attack".
You see a "board" with your warrior ant count and the colony population count.
Every second a new attack in called from the client causing counting on the server to take place
- Both sides have casualties
- There might be cave in-s casing colony capacity decrease and loosing ant on one or the other side.
The attacker may stop the attack stopping the fight.
If one or the other side looses all ants the fight is over.

A defender may also be on location and can then attack the attackers warrior ants by him/herself by attacking the, on the map, exposed colony attacker. Even if the attacker stops the attack.

By smashing ants on the map a player can kill enemy ants too, one at a time.
