142.5mil employed by the US military…either you mistyped, or I’m missing something. That number approaches half the US population of 330mil people.
That puzzled my brain as well, however it comes straight from the horse's mouth
Of course the US military is not just active in the states, there are bases all over the world employing people and the US has many overseas territories as well.
This is a comparison of civilians (143m) and active military (1.3m). It does not state that 142m are employed by the military. You can tell that's what they mean because of this quote:
"In 2017, civilian workers outnumbered military personnel nearly 110 to 1."
