Chavez is a Navy SEAL in the U.S. Navy, stationed in Afghanistan alongside Trevante Cole.
Contact with aliens
Chavez is stationed at a combat outpost in Kandahar Province, Afghanistan, when his unit loses contact with another squad and goes searching for them. They arrive at a village, where the villagers point them towards a school. And from the school, they go to the squad's last known whereabouts, where they come into contact with unearthly resistance.
Recovered by Trevante
After their encounter with the aliens, Chavez somehow ends up in the basement of a medical clinic. Trevante manages to track him down and carry him back to the truck, all while under enemy fire.
Chavez' body is taken back to camp by Trevante and buried nearby.
