I caution against putting too much weight into the statement that insurgents "only fight when they have the advantage". My experience is that small cells will attack larger units in hit and run in order to slow them down and to allow a "swarm" style attack when possible. I feel that insurgents not so much only fights on their terms, as they only fight on their turf. Go into insurgent territory, and they will fight. For all this, it is a very well written paper that reminds me a lot of my own unpublished concept paper on infantry.
