An Army is a team or a group of penguins on Club Penguin that may use snowballs or clothing as a weapon during a war. Alternatively, they may be a peaceful activity group, and compete with minigames, like sledding, or competing with other armies in single-player games through scores. Some armies are terrorists, attacking random players at random times, and fighting Club Penguin itself. Armies will often have a specific uniform so that everybody will be recognized. Some Armies may become allies with each other and form an Alliance.
