A printout shows the velocity of each bullet, measured by an electronic shooting chronograph placed about 3m in front of the rifle muzzle. In the advanced course, trainees are taught to use ballistics data to calculate the path that a bullet will take. A precise charting of temperature, wind and other environmental factors enable snipers to know exactly where their rounds will land at distances of up to 1,000m.
