Throughout the struggle, it was in his logistic inability to maintain his armies in the field that the enemy’s fatal weakness lay. Courage his forces had in full measure, but courage was not enough. Reinforcements failed to arrive, weapons, ammunition and food alike ran short, and the dearth of fuel caused their powers of tactical mobility to dwindle to the vanishing point. In the last stages of the campaign they could do little more than wait for the Allied advance to sweep over them.

One picture taken of a World War II B-17 and crew that demonstrates what a complex group effort it was to keep a B-17 flying. At the front the nine man flight crew. Behind them the ground crew starting with the mechanics, then the bomb supply crew, and the various specialists who ranged from maintaining radios to observing the radios. The flight crew got the glory and the risks, but without the ground crew, and the huge logistical operation behind them, not a plane would have left the fields. When it comes to military operations, the part known to the public, combat, is only a part, albeit the most important part, of a complex team effort. Veterans understand this, but since modern society has few veterans, it is important that the public be reminded of this fact, if they are to have any understanding, especially with current technology, of just how mind-boggingly complicated modern war is.
