Rivera

Sergeant Rivera was a non-commissioned officer in the U.S. Army before the Great War.

Background
Rivera acted as an undercover agent regarding Professor Stuart Campbell's side experiments with the Army, masquerading as an employee at University Credit Union to keep the professor's secret lab within the building secure. On the day of the Great War, he, Leslie Mathews, and Curtis Marsh were present within the lab when the first bomb impacts struck. Rivera ordered the pair to stay inside while he exited to investigate, and to not emerge until he gave an all-clear. However, he never returned.

Appearances
Rivera is mentioned only in Fallout 4.
