Only the Alliance captain and vice-captains can place the alliance fort, which can be verified through the following steps:

- Click on the alliance icon located at the bottom right of your screen.
- Navigate to "Alliance Territory."
- Select one of the available alliance forts and click on "Place."

Once the Alliance Fort is placed, you can finish building it by sending your troops to the fort; the more troops that contribute, the quicker the fort is built.

Keep in mind that the benefits of the Alliance Fort are only gained once the Fort is fully completed and you are within the Alliance Fort border
