Quite historically incorrect. Alexander would not be pleased. He himself named Memnon as one of his greatest opponents. The depiction of the battles was also very amateurish. For one thing, men in antiquity were significantly smaller in terms of height, and the Macedonians fought in the Macedonian phalanx.
The Macedonian phalanx was a heavy infantry formation of great military-historical significance for the states of the ancient Hellenistic era. The Macedonian king Philip II, whose son Alexander the Great made it the pillar of his campaign of conquest through Asia, is regarded as its pioneer. Subsequently, the Macedonian phalanx dominated the theatres of war in the eastern Mediterranean in the Hellenistic successor states of the Antigonids, Seleucids, Ptolemies, Attalids and other ruling dynasties, until it succumbed to the Roman legion from the 2nd century BC.
Formed in battle formation, the Macedonian phalanx did not form a rigidly self-contained army body, but was divided into several divisions that had their own command structures and could act independently. Nevertheless, it drew its strength from the cohesion of the individual divisions, which required a high degree of coordination between the commanders as well as a uniform marching speed of the formations, which was practised through rigorous drills.
The basic formation of the army was a syntagma (group), which consisted of 256 men from the time of Alexander at the latest. These were divided into dekades (limbs) and formed a square of 16 men in width and 16 men in depth. Each member was commanded by a dekadarchos, who, according to the name, was a "leader of ten", probably because in earlier times a dekas had consisted of 10 men. The dekadarchos was assisted by two dekastateroi as deputies, who were the two most experienced warriors in the unit and therefore received ten stateros in addition to their monthly salary. One of them stood directly next to the dekadarchos, while the other one closed off the limb at its end. Each dekas formed a tent community and had a servant and a donkey to transport the tent and grain supplies for 30 to 40 days.
The portrayal of Alexander as a quick-tempered and insane person is also ridiculous. Yes, in ancient times many decisions were cold-blooded, which today seem extremely brutal to us, but for the time it was logical and understandable.
