Warleader was a title used by the warrior caste of the Yuuzhan Vong. It was an unofficial rank used in two cases—one was for Yuuzhan Vong Commanders who were in charge of a single theater of war, but not yet escalated to Supreme Commander. Another was for the leaders of simple squadrons and platoons.
Warleader was also the title used by Garn as leader of the One's warriors.
