"He's coming for us.. we're both gonna die!"
— Brad to Jill, shortly before his death.
Brad Vickers (ブラッド・ヴィッカース,Buraddo Vikkāsu?) was a member of the RPD.'s S.T.A.R.S. Alpha Team. He was the unit's chemical protection specialist and, primarily, Alpha's helicopter pilot. Vickers wasn't much of a fighter, and it is not mentioned as to whether or not he had served in any combat capacity before his recruitment into the S.T.A.R.S unit. His hometown was Delucia.
"The police aren't trained for this kind of situation! What could they do?!?"
— Brad commenting upon the futility of the RPD's defensive measures.
On July 24, 1998, the S.T.A.R.S. Alpha team was deployed into the Arklay Mountains to investigate the disappearance of S.T.A.R.S. Bravo team, who the RPD had lost radio contact with the previous night. After spotting and confirming Bravo team's crashed helicopter, Alpha team landed near the wreckage and proceeded to investigate. Vickers then panicked and abandoned his teammates in the Raccoon Forest after witnessing the death of fellow S.T.A.R.S. member Joseph Frost. Upon regaining his composure, Vickers made multiple attempts to re-establish contact with his S.T.A.R.S. teammates whilst flying over the Arklay Mountains and mansion, however, he was unable to receive messages from the damaged radio carried by the survivors. He later assisted them in destroying the Tyrant (T-002 Model) by dropping a Rocket Launcher from the chopper, and then rescued Chris, Jill, Rebecca and Barry moments before the Spencer Mansion exploded.
Shortly after the incident, in response to pressure from Umbrella, Police Chief Brian Irons had S.T.A.R.S. disbanded. Fearing for his job, Brad sided with his employer over the decision.
Raccoon City Destruction Incident
During the Raccoon City Destruction Incident, Vickers was spotted by "the pursuer" and had been on the run for days throughout the city attempting to evade it. He was presumable infected with the t-Virus after being bitten by zombies that he had encountered earlier on September 28. Eventually, Jill caught up with Vickers at Bar Black Jack, who was fending off a zombie and bitten in the process. He then warned her of the presence of a "monster" in the city, and its hunt for S.T.A.R.S. members.
Later, he arrived at the Raccoon Police Station injured and encountered Jill, once again, at the front gate. As he approached Jill to speak with her, he was cornered by the Pursuer and suffered horrendous damage to his skull. Infected with a powerful strain of t-Virus, he quickly mutated and was able to survive the otherwise fatal head wound, and became a Zombie. Whether he was shot by survivors or left to his own devices is unknown, but he was certainly dead by the morning of October 1 when the U.S. Air Force bombed the city with an experimental thermobaric weapon.
