Bill Martin was a custodian at the REPCONN test site.
A custodian at REPCONN before the war, Martin was working when REPCONN accidentally received a shipment of Stealth Boys. Martin emailed RobCo HQ supply department about the shipping mix up, but not before personally using the Stealth Boys to sexually harass fellow employees. This lead to his immediate termination and the Stealth Boys being sent back to RobCo.
Bill Martin is mentioned only in Fallout: New Vegas.
