Lieutenant General William "Tug" Warchorsky is a Terran Dominion officer and commandant of the Dominion Marine Corps. He served as a commander since the days of the Sons of Korhal fighting the Old Families of the Confederacy, and he claimed the marines he commanded were the envy of military strategists everywhere.
After the fall of the Confederacy, Warchorsky was given a commanding position in the Dominion Marine Corps. By 2505, Warchorsky had become commandant of the Dominion Marines. He was stationed on the Dominion Marine Corps Headquarters on Korhal IV, and operated the DMC Combat Development Command out of the Augustgrad Warfighting Center. Warchorsky reviewed, approved and wrote the introduction to the Dominion Marine Corps Field Manual.
