Squads represent their country of origin. They are one of the core elements of World War Online and joining one will give you access to various features and benefits that you will otherwise not be able to enjoy.
Benefits of being in a Squad
Aside from having a direct group of people to play with, being in a Squad opens the door to many new features, such as:
BattleSupport: Squadmates have the ability to Support each other defensively and offensively in Battle. (Read the Supporting section for more information);
Conquer Capitals: Attacks against Capitals are only available to players in a Squad. (Read the Leaderboard section for more information);
Squad Chat: Squads have internal Chats to communicate. There are also alliance-specific Chats;
How a Squad works
A Squad can have up to 8 members, though some have special roles:
Squad Leader: Generally the player who created the Squad. There can only be one Squad Leader and he has access to every tool in the Squad, including forming and breaking Alliances, accepting new members and choosing Squad Captains or a new Squad Leader;
Squad Captains: They are the seconds-in-command. A Squad can have a maximum of 3 and they have control over many Squad Features, excluding selecting new Squad Captains or Squad Leaders;
P.S.: Each Squad can also have a max of 7 foreign members at any time.
