Without doubt, the Auland Empire is a powerful country. Their royal family's White Wolf Royal Guards is indisputably an elite tier 3 light cavalry. The combined charge of 3 of these armies of Silver-rank mounted troops is unstoppable. Alright, this isn't the Underground World where Gold-rank are treated as pawns. At the very least, the military of the smaller countries that they are bordered with are unable withstand their charge.
Compared to races blessed with longevity, a human's individual fighting prowess is definitely a shortcoming. However, humans are a race that depend heavily on tools and external items to achieve victory (The White Wolf Royal Guards can only reach Silver-rank when coupled with their mounts and equipment). The so-called large countries refer to those who possess an advantage in agriculture, manufacturing, alchemy, magic, breeding livestock and the grooming of talents, that's why they are able to equip and sustain a stronger army and military power.
