We're trying to prepare a battle group for medium-intensity combat across the full spectrum of operations. In one area they could be conducting humanitarian assistance of some kind for a local population, all the way across the spectrum literally ti combat operations of that medium intensity with tanks, armour, and artillery. So that's the broadest range. We try to give them the generics, so we expose them to need and cultural awareness without necessarily exposing them to a particular culture or area of operation. In other words, it adds something they need to think about.
