Callsigns


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

Callsigns are a feature in Call of Duty: Modern Warfare 2. Similar in appearance to nametags, they show up on screen whenever a player gets a kill, completes an objective and so on. They are very customizable, with at least 594 possible titles in game. Titles can be anything from "F.N.G." to "Suppressor" to "Surgical". With the titles come a visual background that has something to do with the title. Also available for customization are emblems, of which there are 294. Emblems are little more than small pictures that are just another way to distinguish yourself from other players.
