These special missions were called “Advanced Force Operations.” Subsequently, these special teams brought in the rest of the Green Berets during an operation called "the Ugly Baby." Then, one of the most significant battles in Special Forces history occurred: "Operation Viking Hammer," where six Green Beret teams along with a handful of CIA and Air Force Special Ops personnel, combined with approximately 8000 Peshmerga, took back hundreds of square kilometers from almost 1000 Ansar Al Islam extremists, and secured a poison production facility of national level significance. This book is the only firsthand account of these essential Unconventional Warfare operations, written by an operator who was there. In addition to describing these historically significant Special Operations missions, "One Green Beret" also details a 15-year career in the Green Berets that includes many unique experiences, such as joint operations alongside Russian Spetznaz on the northern border of Kosovo, and postwar operations in Bosnia embedded deeply with the locals. Mark Giaconia questions everything, and provides a VERY humble, sobering, and human perspective on war, military service, and strategic considerations. One Green Beret is very inspiring, and conveys the author’s personal evolution from gunslinger to educated computer scientist; a true tale of “post traumatic success.”
