I know folks who were making $250k per year as contractors in war zones over 10 years ago. It wouldn’t surprise me if the number is higher now. These were all for skilled jobs that required TS SCI clearances.

$250k is $5k a week for 50 weeks. These folks often didn’t work 50 weeks since generous home leave was frequently given, so $1000 a day may actually be on the low side.

Also note that there are tax exemptions via treaties or war zone exceptions that can make a significant impact on take-home wages.
