The 75th Ranger Regiment is a unique and distinct culture among the American military establishment. They stand alone, even among our other Special Operations forces, as the most active brigade-sized force in the current Global War on Terrorism. Since 9/11, the Regiment has been the only continuously engaged unit in the Army, and has had 40 percent of its number deployed in harm's way for the last decade. Their mission is unique. Rangers do not patrol, they don't train allied forces, nor do they engage in routine counterinsurgency duties. They have a single-mission focus: they seek out the enemy and they capture or kill them. This sets Rangers apart as pure, direct-action warriors.

Army Rangers are not born; they are made. The modern 75th Ranger Regiment represents the culmination of 250 years of American soldiering. As the nation's oldest standing military unit, the Regiment traces its origins to Richard Rogers' Rangers during the pre-Revolutionary French and Indian War, through the likes of Francis Marion and John Mosby, to the five active Ranger battalions of the Second World War, and finally, to the four battalions of the current Ranger regiment engaged in modern combat. Over that period, a standard of professional excellence and the forging of that excellence is distilled in the selection, assessment, and training of today's Rangers.

Granted unprecedented access to the training of this highly restricted component of America's Special Operations Forces in a time of war, retired Navy Captain Dick Couch tells the personal story of the young men who begin this difficult and dangerous journey to become a Ranger. Many will try but only a select few will survive to serve in the 75th Ranger Regiment. Sua Sponte follows a group of these aspiring young warriors through the crucible that is ranger training and their preparation for direct-action missions in Afghanistan against the Taliban.
