The GUSAA, "Army", and the GUSMCA, "Marine Corps", had had fierce rivalries ever since the Rishi Revolution, and they enjoyed facing off against each other. As of 50 BBY, despite the Marine Corps superiority in fighting, the Army had more number of wins than the Marine Corps, leading 660 to 345 games.
