First have you looked into any other companies? i personally wouldn't go with BW when i was in iraq, i could not stand those cowboys. They caused a lot of problems for us.

There are many other companies than the ones you listed. Companies with better standards and better reputations. With that being said....The contractors who are professional do not call themselves mercenaries.. The word Mercenary is frowned upon by the PSD contractors who care about the professionalism of the job.
At this time Blackwater no longer exist in Iraq and still cant get a contract after their name was changed. Do some research and make sure that the company hires professional people who were in special forces. That is of course if you qualify.

Fact from fiction, truth from diction. Go with Blackwater, those a**h**** can rape and kill anyomne they please and never have to account to anyone. You can live out your dream of being a modern day viking, all the killing you want and plunder Uncle Sam while doing it.
