Hehe,

I know nothing of the Cilician pirates, so I can't comment at all on the outfit or "harpoon?" -- a javelin by any other name I suppose.

I would, however, agree with Spino about the description. Troops like pirates or most mercenaries in general were of poor morale. They'll slaughter you with out mercy if they get the upper hand, but if things aren't going so well, they'll rarely stick around.
