The Greek or spartans/athenes? idk the name of those but it were a lot of "Factions within greece, they all united against the persian invasion?
Also, Hoplites were known for fighting in lines, two and two, one with a spear defended by the huge shield his sideman was holding. A group of these was called "Hoplite Phalanx". Agrianos were known fro being elite light infantry, dont ask, just google it. Aichmophoros were spearbearers by the way.
No, hoplites fought in blocks, at least 8 deep. The entire point was to push through the enemy line, and thin enemy lines usually were easy to breach. No, a group of these was called a phalanx. It is redundant to say hoplite phalanx, because phalanxes were always composed of hoplites and hoplites always fought in phalanxes. You cite a good source, but reading an actual book would do all of you good. Books have to be verified to meet a certain level of factual correctness if they are called nonfiction, so they are always better sources. Wikipedia is good, but it is not perfect, even when it cites its source. Also, not all of the greeks united against the persians. Many didn't really care, and only a few city-states-athens, sparta, thebes, thespis, and a couple others supplied troops.
Engineer-no, columns are roman. The greeks did not have advanced architecture.
Look here, and here
Wow, I meant to say arches, but corinthian columns are almost exclusively roman, sooooo... Anyways, greeks did have Ionic and Doric columns.
Just so you know the greeks lacked much resembling a ballista until later times in the siege of syracuse all the athenians could do was build a wall around the city and hope they'd starve, second of all the acropolis was defended by a wooded palisade in the time of the persian wars, though later the had the long walls connecting athens to the port of pyraeus and so on. The chariots were only used as transport for high ranking citizens since greece is not exactly the ideal spot for cavalry combat. for ranged it should mostly be slingers, peltasts/javelineers, and some mediocre archers(the greeks lacked many archers and also the bows of the time period were extremely weak and had trouble penetrating hardened leather let alone the bronze breastplates many greek troops wore.
The siege of syracuse was in 399 bc, if I am right. Cretan and scythian archers were routinely employed as mercenaries in battle in the greek peninsula. The acropolis of athens and that of many other cities had a high stone wall, not a palisade. In the persian wars, the reason the acropolis fell was that
all of the athenians left the city. Athens didn't even put up a fight. Mind you, they know they would have lost.
