NCWGRU:MESGRU ONE

**NCWGRU/MESGRU ONE (Naval Coastal Warfare Group ONE / Maritime Expeditionary Security Group ONE)** has its origins in the Cold War era, when the U.S. Navy recognized the need for specialized forces to protect harbors, ports, and coastal areas. Originally established as Naval Coastal Warfare Group ONE, the unit was tasked with providing security for critical maritime infrastructure and supporting amphibious operations. In 2004, the unit was redesignated as Maritime Expeditionary Security Group ONE (MESGRU ONE) to reflect its broader expeditionary and security mission, including anti-terrorism, force protection, and maritime interdiction operations. Based on the West Coast, MESGRU ONE has deployed worldwide in support of major operations, safeguarding U.S. and allied assets in conflict zones and high-threat environments.
