You want to hear something really fascinating? Fascinating. Alexander the Great arms his armies with the Sarissa, which is this 15-foot pike. Extra long spear. And so when the spear is that long, you don't even hardly need shields anymore. It's this incredibly thing, frontal attack. And that's what he uses to make himself ruler of the known world. And he goes and conquers the Persian Empire, himself kings. This phalanx armed with Sarissa. Romans, different, they they have heavy infantry. They focus more on fighting with short swords. It's get up close and kind of stab. Romans is the other thing the Romans do is on flexibility and subdividing their army. And sticking. The big sticking point comes at 197 BC at the Battle of Cynoscephalae, when the Roman legion goes up against descendants of Alexander the Great, who's using his military system. So this is the new Roman flexibility system versus the old invincible system. Heavily with the long 15-foot poles. And the key moment in the battle is where they lock in clash. Macedonians are gonna win. But the Romans have the flexibility to break off a little section of their army, run around to the side and attack that formation from the side. They tactically superior flexibility. So it's always development and counter-development in military history.
