From Ken: LS and others posted definitions, all of which I agree with. So IMO, we are now performing FID. Period. We are not performing COIN because the US has no insurgents to fight (That is not just a semantic quibble; whose insurgents are they?).

We are using COIN TTP to assist the Government of Afghanistan (GOA) with their COIN operation. We are also assisting them in the control of smuggling and other criminal operations. Well, that's mostly what we say, anyway...
In short we are supporting the host nation in their COIN effort or whatever as part of FID
