You never see actually Brad in the game, you only ever hear him a few times. Of course everyone believes he is worthy of dying seeing as he is the cause of why the Alpha Team is stuck where they are.
Flying off in the teams helicopter, having no luck finding the mansion close by, then finding them and waiting until the mansion’s about to blow up before chucking the Rocket Launcher. Others believe he's the most realistic character in the series, fleeing in the face of danger.
Brad has later returned in both Resident Evil 2 and Resident Evil 3, oddly enough that aside from Wesker, he is one character to appear in a large number of games thusfar. Well perhaps if you count him for the original game that is.
