Stephen Hunter first wrote Point of Impact a couple of decades ago and it is a fictional novel based on Bobby Lee Swagger, a former Vietnam sniper… one of the best. Mr. Hunter was one of the first modern fictional authors to write a novel based on a sniper and for the most part he did a pretty good job. Some of the facts and data were a little off, but he did his research and used some artistic license to make the book more entertaining. The book turned out to be very popular and the movie “Shooter” and TV series by the same name are based on this character and book, though updated with modern conflicts and events. It has also lead to several other follow on books with the same character. Stephen Hunter is a good author and he writes a good story and he gets it mostly right, so enjoy them.
