Sniper: Bulletproof deconstructs and analyzes the little-known sniper events that have occurred when no other course of action was possible. The people who planned the takedowns, or pulled the trigger, share their techniques and bring to light the many factors that had to be considered in each mission: terrain, wind speed, temperature, elevation changes... all are critical to taking out targets considered bulletproof. A sniper has one chance, one breath, to rise to the occasion and save the day... if they miss, there may never be another opportunity. As these never told before stories unfold, the viewer also learns about the high-tech gear each sniper carries on their classified missions.

THE BRAIN is an astonishing voyage of discovery into our last biological frontier. Although today s computers can make calculations in one-100th of a second and technology can transport us outside the bonds of Earth, only now are we beginning to understand the most complex machine in the universe. Using simple analogies, real-life case studies, and state-of-the-art CGI, this special shows how the brain works, explains the frequent battle between instinct and reason, and unravels the mysteries of memory and decision-making. It takes us inside the mind of a soldier under fire to see how decisions are made in extreme situations, examines how an autistic person like Rain Man develops remarkable skills, and takes on the age-old question of what makes one person good and another evil. Research is rushing forward. We’ve learned more about the workings of the brain in the last five years than in the previous one hundred.
