Trivia

 * The naval rank of Lieutenant Commander is at the same pay grade as the Marine rank of Major. Therefore, Major Antonio Silva, the leader of the ODST forces, is actually the same rank as Purdy. However, since she does not specialize in a combat field, he would assume tactical command. Also, it is never directly stated that she is the Chief Engineer of the vessel, but at her pay grade, it is easy to assume that she is the highest ranking engineer aboard the ship, therefore making her the "Chief". It was likely Purdy was directly subordinate to Captain Keyes.
