There are three frequent themes in the long running genre of future war fiction. One is a call for better preparation today (Erskine Childers’ The Riddle of The Sands comes to mind). Another is the group of previously unregarded heroes who save the day; another, less common in recent times, is the ignored secret weapon that helps them. (In one 1930s story I recall, it’s a battleship with infra-red rangefinders and onboard UAVs.)
All three are present in Space Wars: The First Six Hours of World War III, written by a troika of authors including former AvWeeker Bill Scott.
