Blair was a squad leader who participated in Operation: Deliverance.
Having survived the initial landings, Blair was amongst the Rangers who rallied at the bus depot under the command of Captain Winters where they launched a successful, albeit risky offensive to capture the bus depot from Chimeran forces.
During the battle, Blair was ordered by Captain Winters to take his squad and sweep the Southern and Eastern walls. Successfully completing their objectives, Blair and his squad survived the second and third Chimeran assaults.
Alongside all other Rangers who survived the bus depot offensive, Blair was killed after the Chimera launched spire missiles at the depot.
