"there are finite numbers of skilled combatants"

Victor Davis Hanson:

"between 2003-7 American forces took an enormous toll on jihadists. We have heard mostly how many Americans have been lost, rarely how many of the enemy they have killed or wounded—but the aggregate number is in the tens of thousands. Even in postmodern wars, there are finite numbers of skilled combatants—and many of them simply did not survive their encounter with American troops."
