For the past eight years, the U.S. Army's Sniper School at Fort Benning, Ga., has hosted the International Sniper Competition; where elite two-man teams compete to earn the coveted title of "top sniper." In this grueling competition, the participants' precision, camouflage, stalking and observational skills are put to the ultimate test. Eighteen challenging events examine the teams' expertise in long-range shooting, urban combat and covert maneuvering through realistic conflicts and environments. Bringing together the most elite snipers from around the world, the competition showcases thirty-three teams from branches of the U.S. Army, Marines, and Air Force, and for the first time ever includes a law enforcement team-a SWAT team from Pittsburgh, Pa. The international field includes representatives from Canada, Denmark, France and Ireland. Since some military teams are comprised of active special forces, the identities of many of the competitors have been concealed in order to ensure the safety of the personnel.
