Thucydides’ ponderous tome on the carnage of the Pelo- Matthias Kabel ponnesian War is an extended history of the operational adaptation of each side as they strove to gain a sustainable advantage over their enemy. These key lessons are, as he Above: Corinthian helmet, circa intended, a valuable “possession for all time.” 500 BCE In the midst of an ongoing inter-Service Left: Colonel John S.

As we begin to debate the scale and shape of the Armed Forces, an acute appreciation of history’s hard-earned lessons will remain useful. Tomorrow’s enemies will still get a vote, and they will remain as cunning and elusive as today’s foes.
