Name
From AssaultWiki
The console command name sets the player's nickname that can be seen by other players as a form of identification. By default, if one has not changed their name, it will be unarmed. If there are more players with the same nickname, their names will appear as unarmed (cn).
Names can be used to identify where you are from or which clan you are participating in.
Usage
Open the console and type in /name "Xyz", where Xyz is your name. The names are limited to 15 characters with no blank spaces allowed.
Possible screen messages
unarmed is now known as Xyz
Note that if you're the one changing your name, you won't see any messages. Check the scoreboard if you need to verify that your name was changed.
