Galactic Marines
this was one of the primary divisions of the Grand Army of the Republic, sent into battle to secure the frontlines of a battlefield during the height of the Clone Wars. Culled from the 21st Nova Corps of the Outer Rim Sector Army by Jedi Master Ki-Adi-Mundi and Commander Bacara, the clone troopers of the Galactic Marines were considered to have been among the toughest of the clones produced on Kamino, as demonstrated by their heroic efforts during the Battle of New Bornalex.
