The Hunn is armed with a spear, bow, short sword and knife. Instead of a sword, the Turk has a long saber (they have already learned how to make them) and armor made of metal plates sewn onto a leather robe (the Xiongnu usually had bone plates). The Mongol wears chain mail or lamellar armor, a wrought iron helmet (among the Turks, it was rare and only riveted).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
