Yeah, I don't know what we really add to the "coalition" training piece WRT RIVRON. No doubt there is some good will there. What is SWCC up to these days? Could they absorb that once a year training mission for these countries?
In terms of the "not to be spoken of here" stuff that RIVRON does, that mission is broad, not at all unique to small boats, and is easily absorbed by many other assets.
My bottom line: the party line is that "RIVRON is a SOF mission executed by conventional forces." BULL. Either let SOF absorb the mission if it's so important; or abolish it completely because it's clear that it's not been properly executed by said conventional forces.
RIVRON is not a SOF mission.
Navy inherited it from USMC conventional forces (manned with grunt riflemen/machine gunner MOSs) because the USMC wanted their grunts to go back to doing infantry shit, instead of boat shit.
For the traditional riverine mission, it revolved mostly around:
Waterborne Guard Post. Anything from interdict waterborne traffic (riverine VBSS) in broad daylight in highly trafficked waters to set up somewhere at night to ambush the shit out of some insurgents who want to sneak around on a river because Coalition ground forces don't usually operate there.
Cache searches. You deploy the organic ground element, roughly squad size, who search possible cache sites either on the river itself or within LOS of the river.
Infrastructure Protection. Patrols near Haditha Dam.
Combat Taxi. Drop off some infantry (or sometimes SOF) dudes who need a ride.
It's what they did in Iraq, and that was just a repeat of Market Garden/SEALORDS in Vietnam.
SWCC doesn't do that, because SWCC's job is to support the SEALs...and both SEALs and SWCC are (or at least were) too busy doing high speed shit to go poking around a river for weapons caches or inspect busy river traffic.
The only real overlap with SWCC is that they both use boats, one of the boat types is the same, and both units are to be capable of performing a hot extract for friendlies under fire from a river or beach. Or at least we used to...I have doubts that they're still doing live fire exercises in support of troops in contact in the current environment.
I do agree that you need to either do it right, or not bother doing it at all. The mission set is too risky to half ass it.
The other stuff, other assets could absorb it, but small boats do offer some unique advantages.
There's also an intangible benefit to the community in developing leadership in its JOs, IMO. And you learn a LOT about operational planning and joint ops.
