Radner

Captain Radner was one of the marines that had come with Colonel Everett to support the Atlantis Expedition hold out against the inbound Wraith Hive ships. He stood as a Railguns helmsman and later joined search parties to hunt down intruding Wraith after the first Dart wave. Stargate Operations lost contact with him during the second dart wave. It was unknown if he was a victim of wraith feeding or if he had survived. (ATL: The Siege, Part 2 and The Siege, Part 3)
