Define "Armed Forces"

Rosa Brooks says the line is blurring even further between civilians and the military:

Complicating matters even more, the decline in the military's tooth-to-tail ratio has been paralleled by a rise in civilian organizations (public and private) engaging in what look suspiciously like traditional military activities. The CIA has gone kinetic, for instance, with paramilitary forces that engage in direct action, often working hand in hand with military special operations forces. And for-profit private military companies increasingly place civilian contractors in jobs that resemble combat positions in all but name.
