I have a lot of respect for Patraeus, who showed up at my friends' memorial service after they crashed in Afghanistan. He still wore his 101st Airborne Division (my unit) patch, which was apparently always his favorite unit. Things seemed to be getting quite a bit better under him. It's certainly a loss for the Army.
He's a conventional Soldier, but he'll do well no matter what he does. I'd like to see him run for president, some day.
Gates pretty much demanded to shake hands with everyone in my company during his visit late last year after he heard a couple of stories. He always seemed pretty level-headed to me, and you could count on him to make the right decisions after listening to those who knew more about the situation than him -- certainly a change from what we were used to.
