This manual talks about advanced rifle training for the observer and or sniper. This manual talks about ballistics, and the various factors involved with shooting at long distances. No matter what range you are shooting at, the basics remain the same, sight alignment, sight picture, trigger pull, breath control, proper shooting position and natural point of aim. If you do not have the basics, you are not going to engage targets effectively. The U.S. Marine Corps qualifies all Marines at 200, 300, and 500 meters. These qualifications are done with open sights, no scopes. Good reference, but nothing helps more than putting rounds down range…practice, practice, practice.
