Nicholson was a squad leader who participated in Operation Deliverance.
Having survived the initial landings, Nicholson was amongst the Rangers who rallied at the bus depot under the command of Captain Winters where they launched a succesful, albeit risky offensive to capture the bus depot from Chimeran forces.
During the battle, Nicholson and Kimble were ordered by Captain Winters to secure the Northern wall as Chimeran forces had managed to breach through them and eliminate Swain and his squad, who had been previously ordered to secure that wall. Successfully completing their objectives, both men and their squads then redeployed to assist Blair in securing the Western wall.
Like all Rangers who had survived the bus depot offensive, Nicholson was killed after the Chimera launched spire missiles on the bus depot.
