Private Stamovich was a member of the United States Colonial Marine Corps. He was a member of the USCM security detail stationed at Hadley's Hope on Acheron in 2179. He was subsequently involved in combating the Xenomorph infestation at the colony.
Stamovich was part of a small group of disruptive Marines at the colony, led by Sergeant Marvin Draper, who were in conflict with their new commending officer, Captain Demian Brackett. He was lost during the ill-fated assault on the Xenomorph Hive inside the Atmosphere Processing Plant, although it is unclear if he was killed outright or taken and later impregnated with a Chestburster.
- Stamovich is labelled a Corporal early in the story, yet later his rank is given as Private.
