Explorer Search and Rescue
（重定向自ESAR）
Explorer Search and Rescue (ESAR) are teams of Explorers in the Learning for Life program of the Boy Scouts of America who are trained and deployed for search and rescue missions. Well-developed ESAR programs emerged in the state of Washington in the mid-1950s (Beginning with King County in 1954) and were followed by others in California and elsewhere. The rugged, mountainous terrain of these areas often require massive amounts of manpower for proper searches for missing people, not to mention their rescue and evacuation from remote areas. The ESAR mission has also expanded over the years to include urban search and rescue and other disaster-related disciplines. Many ESAR groups also provide wilderness safety training to the public.
