This item popped up on the latest SW Journal article 'Thoughts from Khobar: Where Do We Go from Here?' as:
The Army is standing up regionally aligned brigades (RAB) for advisory and theater-cooperation missions in Africa beginning in 2013

The first of up to seven new Army units, created to train and help foreign militaries will be operational by the next fiscal year. The first of these "Regionally Aligned Brigades" will be assigned to Africa Command, but will be stationed in the continental United States....

The brigade will be responsible for working with foreign militaries on stability, security and training operations and should be ready to go by by fiscal 2013....These military cooperation units will be roughly the size as a brigade combat team....
I appreciate this idea / plan was floated openly in a briefing at the US Army Association and was not picked up on SWC. I hesitate to say the article refers to a UK colonel giving part of the briefing.

How AFRICOM would "sell" this brigade's use in Africa eludes me.
