We talked last week about Garrosh Hellscream as a tactician and strategist. This week, we're going to talk about his opposite numbers. Unlike Garrosh, Varian has become the Alliance's supreme military commander more by default than acclimation or appointment. The Horde started as a military organization, and its chief executive is named 'Warchief', so the job of commanding the Horde's military forces naturally comes along with it.
The Alliance technically doesn't have any sort of chief executive figure. Varian Wrynn is King of Stormwind, not the Alliance as a whole. While Stormwind's military forms the backbone of the Alliance's military forces, it's fair to say that Varian has become de facto head of the entire Alliance military less out of a desire from anyone to see him in that role and more out of reluctance from anyone else to step forward and attempt it.
