Not on the Destroyers but on the Boxer, an Amphib that showed up about 12hrs after the Halyburton.
They are part of the MEU's STA Plt. But 9 Snipers, 8 Scout-Snipers and their SS Qual'd Plt Sgt, a Gunny, have been assigned to support the Anti-Piracy Ops throughout the AO & were on scene at the time.
Taking the shots, sure they could've easily taken the shots.
But to manage & manipulate the Hostiles like that to make the shots so easy, no.
There are only 2 other units in the US who could've handled the entire Op w/that much skill and they are both dedicated to HR.
