Callsigns


 * For callsigns in-game characters have used, see Category:Callsigns.



Callsigns are a new feature, introduced in Call of Duty: Modern Warfare 2. They are similar in nature to nametags, and are used to help distinguish individual players, who can customize their Callsign according to their unique personal tastes and preferences. A Callsign features several elements: the name of the player, a title, an emblem, their level, their rank, and their clan tag. The Callsign of a relevant player can appear on the user interface several times at particular events during multiplayer gameplay: whenever a player kills or is killed by another player, when a player completes or affects an objective in a match, when a player is being spectated (including killcams), or other significant events such as calling in major killstreak rewards or executing multikills.

Players can choose from at least 594 possible Titles--a word or phrase accompanied by a relevant background image--to use with their Callsign. In addition to Titles, players can also choose from 294 Emblems--small icons that appear to the right of a player's Title in a Callsign. While some are unlocked initially, most Titles and Emblems must be unlocked by completing various challenges in-game.
