Coastal Riverine Force (CRF) operates in harbors, rivers, bays, and along coastlines. The primary mission of CRF is to conduct maritime security operations by defending high value assets and critical infrastructure from enemies through both non-lethal and lethal means. When ordered, CRF is also capable of conducting offensive combat operations. CRF consists of units that are trained and equipped to operate in all weather and conduct missions such as port security, small unit insertion/extraction, and command and control for supporting units.
