The Starfleet 4th Marine Regiment (known to troops as the Fighting Fourth) was a Starfleet marine regiment military unit consisting of numerous Starfleet Marines, based aboard the USS Landover. In the 23rd century's Four Years War between the Federation and the Klingons, the 4th landed on Joia V shortly before the destruction of the Landover by Klingon forces, resulting in the loss of all 4th Regiment officers. The command of the mission on the planet was then left to Master Sergeant Randall Robor-Wheeler. (FASA RPG module: The Four Years War)
