In the combat flight sim hobby, like any other facet of multiplayer gaming, one needs a callsign. I'm a U.S. Navy veteran who served as an intelligence specialist aboard a CVN during the Cold War and Gulf War. My focus was on Soviet and Warsaw Pact military operations and Strike Warfare Mission Planning. We were referred to as "Spooks" because we worked in the shadowy realms of CVIC and SUPPLOT—spaces that were off limits to all but a handful of the crew. It's a great callsign because it's a single syllable, it's easy to remember, and it's easy to say for my friends whose first language isn't English.
