The match between King Gwanggaeto and Alexander... The reason why the winner is bound to be in Goguryeo.

 As far as I know, Goguryeo is the "Buddha's Byeoljong, One branch. I think so and I agree with Sohae. Buyeo is a country surrounded by nomadic peoples on all sides. The nomadic people have used various methods to effectively deal with horses, and the most representative is the "invention of the back." Goguryeo, which had the temperament of the equestrian nomadic people, also accepted the monk's robe early on. Whether the inflow route of the stirrup was from the Hunno side or the Chinese side, it was accepted "early" anyway. The cavalry with this "back" can handle the bow well on horseback and effectively and stably fight on horseback. And since you mentioned Gwanggaeto the Great, let me tell you based on this era. King Gwanggaeto ascended the throne and conquered several countries right around him. King Gwanggaeto fought constantly to secure iron. As soon as they have the iron, they are all used to cultivate strong troops. The army is an ironclad armed with iron all over its body. He is the ironclad soldier who holds a long spear and wears a powerful ironclad that does not work with a bow and a spear, enters the enemy camp, stirs it around, and destroys the ranks. Also, the number of cavalry has increased. During King Gwanggaeto's reign, Goguryeo dominated a place called Jidouu.This place is useful as a horse production area and was famous... I know that cavalry is more effective in combat than infantry. In the field... Alexander Macedonian cavalry may be faster in mobility than Goguryeo cavalry, but Goguryeo cavalry is absolutely ahead in combat utility. In addition, Goguryeo army had a long range and a powerful "Maekgung". Goguryeo is definitely ahead in the confrontation with the defenders, and the one with a high proportion of the tactical system using the bow is definitely advantageous, right? This is the sound of Goguryeo. As you mentioned Blade Hae in detail earlier, I don't think there's anything more to say about Alexander. I won't mention it. And King Gwanggaeto was actively engaged in conquering activities. I don't know that he made such achievements simply by his one-man show. An effective tactical system and the composition of the military were used. Goguryeo, who studied "how to win battles with other countries," had a factor that could not be beaten by any other country. Of course, I'm not saying it's a complete victory. But at least the country that tried to do that is sweet. Goguryeo used tactics and troops to win the battle against Chinese troops and nomadic peoples, who had a large number of weapons and had a high proportion of horsemen. It's a way to confront equestrian soldiers, and others have to take a few steps closer to attack, but I attack more safely from behind, and the killing power is also fast and effective tactics. I think this was the tactic of the Goguryeo army. Macedonia, who was vulnerable to cavalry attacks. It is bound to be weakened by the attack of Goguryeo troops, who sought ways to win the battle against the horsemen with strong cavalry.
