After a near 35-year hiatus, the US Navy (USN) is returning in force to the riverine mission it quietly abandoned shortly after the Vietnam War. The Riverine Group, a battalion-sized unit conceived 17 years ago but implemented only after 2005, has stood up Riverine Squadron-One (RIVRON-One) and is in the process of standing up RIVRON-Two, using mainly ships borrowed from the US Marine Corps and navy special warfare units.
This is good. It seems unfair that there should be any bodies of water on this planet that our Navy does not dominate.
