All,

I am currently working on a tasker that requires I define the terms Stability Operations (SO), Security Force Assistance (SFA), Counterinsurgency (COIN), Foreign Internal Defense (FID), and Irregular Warfare (IW) in relation to the effect/scope of each term on the conventional force.

I have a lot of working material from inside the army - but would like to solicit input on how this community views the venn-diagram intersection of the above in Army doctrine and terminology (vis a vis 3-0, 3-07, etc.)

Thoughts?
