I was contacted by Blackwater several months ago after I retired and was offered a job over there as a technician working on their comms gear. I turned them down twice. The money would have great...over $80k for a six month deployment.
The reason I didn't do it is because they are mercenaries. I served my time on active duty and I know a few people that signed on with Blackwater and the ONLY reason they did it was for the money.
Now I have a job as a civilian contractor working for the Coast Guard but the big differance between what I do now and what Blackwater does is this. My job is to directly support the products that the Coast Guard uses in it's everyday missions. I work hand in hand with Coast Guard personel to help maintain the systems I work with. Blackwater doesn't. They work outside of the military and do their own thing and that wasn't something I felt comfortable doing.
Contractors can be very helpfull to military operations in a support role. Company tech reps and stuff working on government contracts don't take military jobs away from the troops. They support the equipment produced by their company that the military is using. I see nothing wrong with that, but to be called a contractor while engaging in actual combat operations that the military has no control over is a bunch of crap.
Personally I'd love to see Blackwater kicked to the curb. They have no reason to be over there. If diplomats and VIP's need protection, that is what the State Department Security force is for. If they don't have enough personel to do the job then they need to hire more people. At least then they will be working directly for the government.
