The Marine Corps has been America's expeditionary force in readiness since 1775. We are forward deployed to respond swiftly and aggressively in times of crisis. We are soldiers of the sea, providing forces and detachments to naval ships and shore operations. We are global leaders who develop expeditionary doctrine and innovations that set the example and lead other countries' forces and agencies in multinational military operations. These unique capabilities make us "First to Fight," and our nation's first line of defense.
