The PROMIS series is an on-going issuance of short stories written by Jack Murphy, a United States Army Ranger and Special Forces veteran. It is the background of the author that gives the books their authenticity and feeling of immediacy and intensity.
Sean Deckard is a Studies and Observation Group (SOG) Team Leader, the one-zero of Reconnaissance Team Key West. The book starts (as do most Murphy books) right in the thick of things with a hot extraction of a downed pilot. The mission is going from bad to worse, and several casualties are suffered before success is achieved. This is a hallmark of the PROMIS series, quick hits of action that flow from one to another to build the story. Murphy has a way with violence that reaches closer and closer to Stephen Pressfield and similar masters of the genre.
This is not like Reflexive Fire, which spends pages developing background characters, describing things in detail, outlining the deep plans of other actors. The book focuses entirely on Deckard, and you can feel him running ragged around the edges as he hops from mission to mission, doing his best to win the war single handedly. When he eventually participates in striking a decisive blow, he is sorely disappointed by the reaction, and things close with a bang.
The book is best described as "special operations without cool toys," in that the soldiers are all superb warriors, but do not yet have access to the technology that we so associate with top tier SOF units. It is a quick read, and well worth it. I own a Kindle and could have loaned it out for free, but the product that Jack Murphy produces is well worth paying for.
