if there's anything that describes the US military brass, it's "relentlessly competent"?
This goes back to (at least) WWII, where there was a saying among the ground troops that "When the Germans flew over, the British ducked. When the British flew over, the Germans ducked. When the Americans flew over, everyone ducked".
There's a - possibly apocryphal - story of Patton nominating some USAF pilots for the Iron Cross after being strafed by them three times in one day. Less apocryphal is that more US troops, including the highest-ranking casualty in the war, a Lt.General, were killed by USAF pilots than Luftwaffe pilots during D-Day (Operation Cobra, in which US ground troops fired at their own planes in frustration).
