在阿富汗和伊拉克都打过仗，官职Major. 军队资历够了： high enough to lead a good size unit and knows the brutalities of war at a personal level, but not so high that he’s turned into a political figure, which generals tend to be.

We want a SecDef who knows the personal sacrifices of wars, not a representative of the Military Industrial Complex and warmonger such as Rumsfeld.

我认为他和肯尼迪越战期间的国防部长Rober McNamara从学历(Harvard)到军衔(Lt. Colonel)都很像.
