Story Mode, and Status
A Special Forces soldier with a very similar appearance to Sergeant can be seen piloting a helicopter containing Johnny Cage, Sonya Blade, Raiden, Kenshi, as well as several soldiers towards Raiden's Sky Temple. Johnny discusses the landing zone with "Sergeant". During the flight, the helicopter is attacked by Scorpion, who throws his spear into the face of "Sergeant", most likely killing him, promptly dragging him through the cockpit window, before attempting to deal with Cage and Kenshi.
It is unknown if this pilot was Sergeant, although it is likely, due to the identical design.
