She was a member of the United States Corporal Marine Corps and participated in the mission on the moon LV-426 to investigate the sudden loss of contact there and was therefore subsequently involved in the fight against the Xenomorph infestation there. She had a close relationship with Private Drake. At first she thought, like the rest of the Marines, the mission to LV-426 was a waste of time. During the first catastrophic encounter with the Xenomorphs, where many of the Marines were killed or kidnapped for infestation, she learned the hard way not to underestimate them.
