Chester is the callsign of a Rafale pilot in H.A.W.X. squadron. He provided close air support for a Ghost Recon team in Mexico. He was fired on by a SAM, but was able to outmaneuver the missiles and launch his ordinance at enemy tanks.
Chester appears in the trailer for Tom Clancy's H.A.W.X., and it is unclear if he appears in the main HAWX universe.
