Battalion Aid Station Capability in the Future

We are a changing Army and plenty of ideas exist about where combat medicine needs to go, based off the needs of the war fighter.  We have seen a change in the Surgical teams down range in Afghanistan and a change for the Combat Support Hospitals are coming.  My question is with the way deployments are changing and how the Army is looking to regional align, such as Special Ops does, what change does the Army need to do to the Battalion Aid Stations?  What requirements should we add or take away inside the Maneuver BDEs?
