"But as for a SOF background giving someone some special skill in commanding a multinational force at the 4-star level - I just don't see it. A good leader will be effective in any setting within the bounds of his profession - and not all good leaders opted for the SFAS try-outs. Many stayed in their branch (Petraeus, Odierno, etc)."

Brother I couldn't have said it better myself. As much as I love my SF brothers, I don't think they have the market cornered on leadership. When you're talking about a 4-star running operations in Afghanistan, he better not be thinking like a tanker, grunt, or snake eater. He has to put ALL the pieces together, including diplomacy to be effective. It takes a very special leader to do this. The great ones are rare and in my opinion are not concentrated in any one branch.

Having said that, I do think he'll do a great job, but time will tell.
