The United States has merged Maritime Expeditionary Security Squadron (MSRON) 4 and the Riverine Squadron (RIVRON) 1 to form the Coastal Riverine Squadron (CORIVRON) 4. "We will always look back with pride at what we and our predecessors have accomplished," said, Cmdr. Blane T. Shearon. "As we come together, now is the opportunity to write the next chapter in the history of the Navy's small boat units". Shearon added that what matters now is how good the force is today and how much better CORIVRON 4 will become in the future. Combining the two forces bridges the gap between traditional Navy blue-water operations and land-based forces, providing port and harbor security for vital waterways and protection of high-value assets and maritime infrastructure. CORIVFOR is a component of Navy Expeditionary Combat Command (NECC) and a core Navy maritime capability able to defend high-value assets against a determined enemy and, when ordered, conduct offensive combat operations by providing maritime expeditionary security and riverine operations throughout the green-water and brown-water environment.
