Home Grown Iraqi Commando Units

Reading Riverbend's blog, I came across the name Badir’s Brigade. I assumed it was a local Bagdhdad militia. Today at Phil Carter's site I found this article that talked about such locally formed units. The pop-up units although less in number are more succesful when it comes to loyalty than their US trained counterparts, and the US is working on trying to co-opt them. It is an interesting issue, but surely raises questions about what responsibilities and legal status such units have.
