AmMerc has a great piece on logistics HERE
".....are there any suspicious areas of inactivity? People don't like to fight where they live if they can avoid it. If the only difference between area A and area B is the level of conflict, it bears looking into. This is where the military intelligence guys can come in handy, finding out what the scuttlebutt is on why neighborhood A is quiet."
As Napoleon Bonaparte famously implied; logistics is the lifeblood of warfare.
