A Republic marine served as a combatant within the military of the Galactic Republic. Before the Republic transformed into the Galactic Empire, Imperial Grand Admiral Josef Grunger was previously a Republic marine.
The article "Who's Who: Imperial Grand Admirals" from Star Wars Insider was first created for the Star Wars Gamer publication, but it was never published due to the magazine's termination. Its original title was "Dirty Dozen: The Imperial Grand Admirals." When the piece was used again in Star Wars Insider, some information was left out, notably the fact that Grunger was an "ex-Republic marine."
