Here is a link to some interesting photos from our Chinese friends along with some comments regarding a convoy operation off Somalia.
The surprise, for me, was to see the mass of suspected pirates, not one or two, but a swarm of small boats.

An abundance of targets.
Perhaps a hand-crank 57-mm Hotchkiss could make a comeback. http://en.wikipedia.org/wiki/Benjamin_B._Hotchkiss
Bill, are you thinking about the 37 mms in front of the Academy? Any old Gatling gun would do.
I am not sure what is in front of the Academy. I do know the RCS used the Hotchkiss 57-mm. I do not recall it mounting the 37-mm. I’d have to check.
Anyway, a target rich environment. I think a half dozen guys with M14 would work–that is if they knew how to shoot them.
