Kimble was a squad leader who participated in Operation: Deliverance. During the battle in the bus depot Kimble, and Nicholson, were ordered by Captain Winters to secure the north wall after Chimeran forces had managed to infiltrate the wall as Swain, the man who was suppose to sweep that wall, was killed. Kimble and Nicholson did manage to secure the north wall and then aided Blair to secure the west. Kimble was presumably killed after the Chimera launched spire missiles at the depot.
