Not a lot of background info here. Is being purported to be a group of Private Military Contractors aboard an unidentified merchant vessel off the Somali Coast. At about 40 seconds into the video you see a small fast boat approach danger close and attempt to board or at least menace the much larger merchie. A team of 2-4 PMCs armed with semi-automatic AR-15 platforms engage the small boat extensively and drive it off. Note the PMC’s sandbagged defensive position, nomex gear, and other interesting pieces of kit. Also it looks like they have a non-lethal LRAD set up, although you cannot tell if it is being used or not.
