Supreme Commander

The title of Supreme Commander has traditionally always designated the Galactic Imperium Officer executively in charge of all of the Navy and Army. In the Galactic Imperium, the one who held this rank was also second in command of the Imperium. This role was assumed by Patton during the first decade and a half of the Imperium's years. When Emperor Ramsay died at the end of the Shrike War, Patton took charge of the Imperium but kept the title of Supreme Commander. From then on, the Supreme Commander officially became the rank of the leader of the Galactic Imperium.

History
The position of Supreme Commander as with George Patton, evolved to the position of the Commander and Chief of the Empire, with everything under his central command. This put him in a position to make decisions for both the military and the general populace. Unlike previous versions of Supreme Commander, he had no Moff council to interfere with his command, and stood as the singular ruler of the Imperial Remnant.
