Kirby, an Aircraft Rescue and Fire Fighting technician with Marine Wing Support Detachment, Marine Corps Air Station Kaneohe Bay, Hawaii, Pacific Division Team, stands in preparation for moving to the sitting position upon firing the National Match M16A4 service rifle with iron sights at the 300-yard line rapid fire during the individual rifle portion of the 2014 Marine Corps Match Championships from April 14-16 aboard the Weapons Training Battalion ranges at Stone Bay. Kirby is one of 84 competitors, and they competed in three different categories. The individual rifle match, the individual pistol match and the team rifle and pistol match. The individual rifle match and team match are shot from the 200-yard line, 300-yard line and 600-yard line. The match rifle weighs approximately 17 pounds, with a stainless steel barrel with both weighted hand guards and butt stock. During competition marksmanship, competitors are supplied with unique shooting jackets and non-slip leather rifle slings that provide additional stability, and long-distance scouting scopes to sight shots at distances more than 600 yards.
