This one is a bit off topic, but I found this fascinating. These guys have a well defined business model.
To be eligible for employment as a pirate, a volunteer should already possess a firearm for use in the operation. For this ‘contribution’, he receives a ‘class A’ share of any profit. Pirates who provide a skiff or a heavier firearm, like an RPG or a general purpose machine gun, may be entitled to an additional A-share. The first pirate to board a vessel may also be entitled to an extra A-share.
At least 12 other volunteers are recruited as militiamen to provide protection on land of a ship is hijacked, In addition, each member of the pirate team may bring a partner or relative to be part of this land-based force. Militiamen must possess their own weapon, and receive a ‘class B’ share — usually a fixed amount equivalent to approximately US$15,000.
