Dave Johnson was a soldier in the Bioterrorism Safety Assessment Alliance's West Africa branch, serving as a marksman for Captain Josh Stone's Delta Team. In 2009 he participated in the BSAA mission to Kijuju, where he was among the casualties.
Prior to his BSAA career, Johnson was an off-road rally driver participating in at least one race at the Rally World Championship. In the BSAA Johnson demonstrated expertise as a sharpshooter, and was provided with a German semi-automatic sniper rifle, a Heckler & Koch PSG-1.
In March 2009 Johnson's unit was ordered into the Kijuju Autonomous Zone to reinforce SOU agents Chris Redfield and Sheva Alomar, after the deaths of the Alpha Team. Johnson was able to shoot a motorcycle-riding Majini during the rescue. Following this, Delta Team established base camp at a village in the savannah outside of Kijuju itself. Johnson later drove to the quarry in the team's Gambit to pick up agents Redfield and Alomar, escaping a surprise attack on the camp by a Ndesu. Johnson returned after picking up radio chatter on the attack, but arrived too late to save anyone. He was then killed by the Ndesu while examining the body of one of his comrades.
- He was somewhat a humorous character and seemed to be a prominent character compared to the other members of the BSAA, excluding Josh Stone.
