Falcon is a Kurdish owned outfit which supports both coalition and Kurdish specific interests
I'd say that pretty much covers it.

PMCs are expanding to fill other roles - its getting more grey not less. Where there is a need and some initiative, there is a way to make some money. However as far as any PMCs go, I'm not sure I agree with the word "support" in the way I would normally apply it to military relationships.

There are some good people working for Falcon and the other PMCs - but I think the word "contract" is a better description. It provides a pretty set left and right limit for a "service" vs. a supporting relationship such as say a support BN to a line unit. The motivation is different (even if the individual working that PMC would like to do more) as well.

They are useful, but that doesn't mean there are not disadvantages to using them, even if you don't see them up front.
