Warchief
From WoWWiki
The Warchief, or War Chief, is the military leader of the Orcish Horde, similar to a king or Supreme Allied Commander among humans. The post is an ancient tradition, but was forgotten during the civil wars that plagued Draenor following the defeat of the Draenei. After the Horde crossed into Azeroth, Gul'dan revived the office to gain control of the orcs. On Draenor, Ner'zhul took the title in the event Gul'dan should ever return. The Warchief is now the title of the Horde's supreme leader, though his duties no longer include simply war.
In Warcraft: Orcs & Humans, it is a rank you can achieve.
