If I was a little younger I would go. I bet they pay "Haliburton/KBR money" and if you stay 18 months it is all tax free. On these types of jobs I doubt there is much to spend money on in country so it will pretty much all go in the bank. I tried to get IBM to send me to Vietnam in the 60s to work on mod 30s and 1401s but the list was too long and I never got close to the top. That deal was 166% of your pay, tax free and expenses.
