The United States has not spent $ 300 million a day on war in Afghanistan.

Yes, I think you better had, since you’re already off by a factor of 10 - it’s 800 000 servicemen and women, not 80 000.

Hi
A total of 700,000 troops have served in Afghanistan over the past 20 years.
This means, for example, that every soldier has served in Afghanistan for one or two years.
I estimate that there has always been an average of 100,000 staff in Afghanistan.

And in what do you base these estimates?
