Ace Combat: Assault Horizon/Callsigns

Callsigns are a new multiplayer concept introduced in Ace Combat: Assault Horizon. They are codenames used by lead players to represent their squadron in battle. Before each match, the squadron leader can change their wing's callsign through the "Call Sign Settings" option. Players start with a basic "Alpha"-type callsign. Additional callsigns can be unlocked by achieving objectives, such as earning a particular gameplay bonus.
