Recruit
Each player in the game is assigned a unique Commander Code after installing the game. You can invite other players to be one of your commander if you know their Commander Code. Alternatively, other players can invite you if they enter your personal Commander Code. But these invitations need to be manually accepted or rejected. You will get notifications when someone sends you an invitation
To find players interested in joining your military, you can use the game's official Facebook page http://www.facebook.com/BattleCryLive
Commander Code
Commander code is the unique identification provided to every player. It can be used to recruit commanders into your Military Unit. Commander code will be relevant to recover your account in case if you loose access to your account.
