Koguryo and Sui fighting forces?

 The Suseo says that the total number of troops invading Goguryeo was 1,138,800, twice that of heavy soldiers, but the reality is a little different. First of all, the several countries mobilized by the Goguryeo expeditionary forces at that time divided the entire army into 24 general armies and 6 SS armies. However, the first army in several countries at that time consisted of 4,000 cavalry, 8,000 infantry, 8,000 intensive and reinforcements, and 8,000 scouts, each of which consisted of about 20,000 soldiers. Based on this figure, the number of counties in Sui is 30 counties x 20,000 = 600,000. In other words, about 600,000 Sui troops were mobilized for the Goguryeo expedition. If you add about 70,000 marines to this, 600,000 + 70,000 = 670,000 people will be added, bringing the total number of Goguryeo invaders from several countries to 670,000. The hypothesis was proved by Lee Ki-hoon, the author of Korean history viewed as war, and David A. Graff, an expert on medieval Chinese warriors and author of Medieval Chinese Warfare: 300-900. In particular, David A. Graff proved that the Goguryeo expedition had 600,000 to 700,000 troops. 1. The total force of the Sui army mobilized for the Goguryeo expedition calculated 600,000 troops. 2. Suseo (the historical book of the Sui Dynasty) was the last emperor to conquer Yangje. The fact that it falls. However, the records at the time did not include large-scale deaths caused by the war. 4. The total number of soldiers mobilized by several countries in the Chinese Unification War was 518,000, but it does not make sense to mobilize 1 million for the Goguryeo expedition. Given that the number of troops mobilized in the Korean War was less than 600,000 due to the fact that they could mobilize more troops than Goguryeo because they were mobilized in a densely populated midfield. I'm holding my back. And if you look at the combat forces of the Sui Dynasty again, only 4,000 cavalry and 8,000 infantry belonging to each army of the Sui Dynasty can be classified into combat forces. Then, since there were about 12,000 combat troops in one army and a total of 30 troops in the Sui Dynasty, the number of combat troops in the Sioux countries was 12,000 x 30 = 360,000, and the number of combat troops was about 360,000. As my superiors pointed out, the Sui Dynasty's 1 million-strong military theory is unreasonable compared to other dynasties in China. First of all, the agricultural revolution rapidly increased the population and failed to mobilize 1 million people to the expeditionary forces in North Songdo, which had a population of 100 million. During the heyday, the number of troops in the Song Dynasty increased to 1.2 million, but the total number of troops included in the Song Dynasty's expeditionary forces was the largest at around 200,000 to 300,000. Even in the heyday of the Tang Dynasty, the total force was 600,000 and the Tang Dynasty itself was less than 1 million. And the Ming Dynasty was the largest country in the Chinese dynasty. In the Ming Dynasty, up to 3.3 million soldiers were registered on the government record. Of course, 3.3 million people could not be mobilized at once. In any case, even the Ming Dynasty, which had such tremendous military resources, had the largest number of troops mobilized for the expeditionary force of 500,000. It is hard to believe that several countries, which were less populous, technologically inferior, and less able to mobilize than the Ming Dynasty, were able to mobilize more than twice as many troops as the Ming expeditionary forces. Anyway, considering the various factors listed above, it is reasonable to have 600,000 to 700,000 Goguryeo expedition forces under Suyangje. About 600,000 is the same figure as the Sui army system recorded in the political affairs at the time, and about the same figure as the 500,000 troops mobilized by the Sui countries in the war of reunification. Even if the number of troops mobilized by the several countries was 600,000, it is enough to make the country lean considering the huge amount of supplies needed for the Goguryeo expedition. There seems to be some exaggeration in the fact that the Suyangje mobilized 2 million people. As expected, according to the governor and the Suseo, the number of people mobilized by Suyangje to transport food for the Goguryeo expedition is about 600,000. It is said that two 600,000 people joined a group of two and pulled a cart with one wheel each (there is a theory that Jegal invented it) and carried about 180 kg of food repeatedly.
