With respect to Tom's comment, I'd add that as Yeosock was ill, he was backed up by DA who pulled Cal Waller out of I Corps Command and rapidly sent him over to be Yeosock's Deputy commander and reinforce the buffer zone -- pure personality based decision (by Powell through Vuono, I'm sure) and a good one. They got someone who could deflect Norm.
thanks Ken! yes now that you mention that I remember Waller's name coming up in that buffer role...
