An Army is a team or a group of penguins on Club Penguin that are organised with a website, uniform, ranks and some form of communication (for example, Discord or Xat). Groups without this organisation are known as Gangs. Some armies 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. Some Armies may go to war with another army, or become allies with each other and form an Alliance.
