I think he actually served as a CSM in a tactical unit beyond the BN level. That's an improvement. Coming out of TRADOC as the CSM is another improvement. He knows the Army and where it's headed. This is a good choice.
He is infantry and has a Ranger Tab. He will be an improvement for the fighting force. I have a feeling he will be focusing on the real issues and not color of your laces of your PT shoes when you are off duty.
