This command will initiate melee combat with the target you specify. Once combat begins, it can be stopped by leaving the room, running away, death of one of the combatants, or certain guild and racial skills. Other players may also be attacked, if you are both registered player killers.
Initiating combat, whether with <kill> or another combat skill, may affect your team alignment and your Jedi alignment. It also significantly affects Ithorian players. Certain skills, such as <insult>, actually cause the target to initiate combat, thus allowing players to avoid these effects.
