Later than I said it would be but here is:
The Logistician
Logisticians are a sad and embittered race of men who are very much in demand in war, and sink resentfully into obscurity in peace. They deal only in facts, but must work for men who merchant in theories. They emerge during war because war is very much a fact. The disappear in peace because peace is mostly theory. The people who merchant in theories, and employ logisticians in war and ignore them in peace are generals.
Generals are a happily blessed race who radiate confidence and power. They feed only on ambrosia and drink only nectar. In peace, they stride confidently and can invade a world simply by sweeping their hands grandly over the map, pointing their fingers decisively up terrain corridors, and blocking defiles and obstacles with the sides of their hands. In war, they must stride more slowly because each General has a logistician riding on his back and he knows that at any moment, the logistician may lean forward and whisper: "No you can't do that". Generals fear logisticians in war, in peace, generals try to forget logisticians.
Romping along beside generals are strategists and tacticians. Logisticians despise strategists and tacticians. Strategists and tacticians do not know about logiticians until they grow up to be generals - which they usually do.
Sometimes a logistician becomes a general. If he does, he must associate with generals whom he hates, he has a retinue of strategists and tacticians whom he despises; and , on is back ,is logistician whom he fears. This is why logisticians who become generals always have ulcers and cannot eat their ambrosia.
