I did serve with Gen Petraeus on two different occassions... The first during OIF I... the second while as CAC Cdr...

I don't know whether he belongs with Sherman, Abrahms... etc... then again in the midst of their heyday, I'd hazard a guess they had as many detractors... far easier to see a great commander in hindsite than it is in plain view...

This is what I can state authoritatively about Petraeus as a wartime commander...
Lazer-like focus on mission command and communicating intent...
Power down authority...
both physical and moral courage in abundance...
Absolute comfort with decision making...
Rightfully tough on staff to get it right (sometimes leading to the reality or perception of mistrust)...
radiates confidence
Green Tab, Green Tab, Green Tab...

As Commander of CAC...
Intellectually rigorous...
tireless....
flat organization (probably too flat for even himself)...
radiates confidence...

All of which I think bodes well for how HISTORY will regard him... as is predictable, one of his greatest strengths is perhaps his blind spot - radiates confidence would probably also be fairly applied to your entire list...

We shall see, as a disclaimer, my service with the man was from a staff perspective (with lots of access)... I can't say I always liked the man, but that has no bearing... always respected though...

My two cents

Live well and row
