The 88th Armor was a battalion in the Republic Military that served during the early days of the Galactic War with the Sith Empire. In 3642 BBY, the 301st Infantry unit was rotated off of the embattled planet of Hoth after aiding the Jedi Knight known as the Hero of Tython in recovering the plans for the Sith Emperor's space station. While the 301st was sent back to the Republic capital of Coruscant, the 88th Armor was assigned to Hoth in their place by General Callan Grayne.
