Samantha Sanchez was a marine in the Confederate Marine Corps. She wore a black buzz cut and had a blocky muscular body. Ryk Kydd considered her very pretty.
As a lieutenant, she was assigned to the Special Tactics and Mission Platoon, 321st Colonial Rangers Battalion during the Guild Wars on Turaxis II. She took the position very seriously. Kydd developed a crush on her. He even tried to give her chocolate, but lost his chance when he "allowed" Sergeant Tychus Findlay of his platoon to steal it.
Sanchez led the platoon during the Third Battle of Polk's Pride. She was killed by a Kel-Morian sniper during a maneuver. An angry Kydd engaged the other sniper and killed them.
