Well for a while after the Najaf battle, Sadr city decided that it didn't want to bear his name.

But then for whatever reason it was changed back.

He was some support in the slum, but it isn't anything near what he has down south.

"He was some support in the slum, but it isn't anything near what he has down south."
Roger. I suspect as you have indicated, his real base is south of the capital.
And it may turn out Sadr City has little signifance in any major confrontations.
I assumed while viewing street maps and sat photos of SC and it's geo location in the capital and exit routes, it could come into play. It obviously is a very tightly packed neighborhood, as far as dwellings go. I may assume wrong. And on at least one point, since it's open to a cordon shutdown, they may not want to get trapped in such an area, that could be surrounded rather easily.
Then again. As jcm1969 indicated, zman's goons used a very similiar scenario in the Jolan district of Fallujah NW corner. Some areas one couldn't even send a A1 Abram into.
Any way, thanks for the feedback.
