Now here's an interesting heresy: Scrivener's Error says,
In every declared symmetric conflict in the gunpowder era, the side with the higher tail-to-teeth ratio has won the conflict. Not every battle; not every asymmetric or undeclared conflict, although even there it's statistically significant in favor of the big-tail forces. But every “war” has been won by the tail, not the teeth.
The short version of this is “Brave soldiers win battles; brave REMFs win wars.”
It just has to be the right sort of tail.
