Ha, Achilles being Brad Pitt is a real deep meme (he was played by Pitt in the Troy movie).
(Also, both of his heels are his weak point, as both heels have an Achilles tendon.)
Scipio using his soldiers disguised as servants to lower the enemy's guard and do reconnaissance was ingenious. Espionage must not have been a strong part of the Roman military, but if it was, Scipio would have written the book on it.
