Pros
If you need to make some money quick this is the only viable option, and beleive me they know that also ..KBR stands for Kan Be Replaced..
Cons
On a scale of 1 to 20 of things you have to worry about in a warzone in Iraq, bullets and mortars are like number 18 on the list. THE PEOPLE you work with are your number 1 threat, everybody will eventually get fired for something, you may pass up promotions just because you are unaware of the co-workers waiting for you at another job site.Over the years I have seen the most honarable people get fired for most ridiculous accusations and in turn have the worst ,have a extended tenure. Its all about who you know , If you have any post secondary education or a skill set that makes you valuable anywhere else I highly recommend you do not put yourself through the KBR experience.
