UPDATE*
Spudman WP confirmed that the gun at the front of the ship is from the ancient PT-76. This brings up some interesting contrast with the way that US Navy Riverine units are equipped. Not only is the Russian design more heavily armed but it also appears to have a smaller crew. If this boat were to come in contact with US Riverine forces and those forces had no or tardy support the results might be in doubt. Maybe Riverine units should equip with Javelin anti-tank missiles in addition to their standard kit. It would give them added punch against shore bunkers, Gun Support River Boats and enemy monitors if the concept is revived somewhere.
