They worshiped him and considered him a being with divine power, so it was an honor to die for the king. Of course, this was not enough to win, Alexander inherited from his father one of the best armies of ancient times, and he carried out certain reforms to improve his army's fighting power. He organized a special elite unit that was the king's bodyguard. He also had a royal guard in the ranks of soldiers, which numbered seven people, the closest associates of Alexander the Great.

He also organized certain changes in the cavalry, and he introduced concrete helmets for the soldiers. His army's power and the backbone of the Macedonian troops rested on the phalanx, the most precious military formation of the Macedonians. Darius' army was tired of the constant conflict with Alexander. Alexander also used intelligence and various raids, which gave him an advantage. Alexander was an excellent tactician and organizer, and he demonstrated that in the first conflict with Darius in the battle of Isa.
