EmeraldAxe: "maybe 1/20 ppl know how many troops are actually deployed right now"
I expect that far fewer than 1/200,000 USAmericans know that figure.
I don't know the answer, and it's not so easy to find reliable averages- of course the figures continuously change slightly as deployments cycle in and out. Even in round numbers, the statistics are elusive. Googling
general reports and
recent changes we could make a very rough estimate, that about 400k total US troops are deployed abroad, including roughly 180k (slowly declining) in Iraq, and roughly 40k (and rising) in Afghanistan.
For all the lack of interest in the numeric aspect, the interest among the US citizenry about how these forces are specifically enhancing our national interests is still more neglected. That they are all out there "Defending Our Freedom" is scarcely challenged.
