ITT: Greatest commanders and generals in history

They had a form of military to beat the Persians of course. Then came the Carthagians who wrecked that style of warfare and the Romans learned from them.

Huh what? I'm talking about the macedonian phalanx supported by companion cavalry and hypaspists at flanks, as well as screened by archers and peltasts.

This is the winning tactical army deployment right there, and later on late medieval/renaissance army brought back this army composition when they re-learned hellenic tactics.

As far as I remember, the only war between an Alexander style army and the Carthaginians was Pyrrhus' war in Sicily against the Carthaginians. And he threw them into the sea and was about to invade Carthage itself when the Sicilian Greeks betrayed him. The Romans had already developed the legionary manipular system around the time of the Samnite wars, before they ever fought Pyrrhus or the Carthaginians.

Macedonian style army does rekt the roman in direct confrontation and only lose due to lack of logistics as well as uneven terrain, and even bad politics.

The Romans copied what the Carthagians used to defeat their phalanxes and used it against the Greeks. Of course the Romans had immense advantages in logistics and numbers but there good reasons the Romans abandoned the phalanx.

If I am correct which I may not be as I know only a little about this antiquity stuff the Romans had formations that were much like phalanxes before the punic wars.

Romans never did pike phalanx, they adopted greek hoplite phalanx with normal spear, so it's not comparable.

It's arguable they were shit in their organization somehow that their phalanx was broken by gaul infantry charge, or the uneven terrain in hilly Italy makes it hard to form phalanx.

I see. I supposed I was getting the two confused then.

Why was it that the Romans never copied the pike phalanx if it was superior?

I dunno, maybe because roman legionnaire works and that they have enough logistics for it to function. Not to mention, they have mercenaries to fill in any gaps.

Again, tactics is nice and all but logistics is king.
