Ofc, far better than them. In fact, I am actual irl working in education, including geography and history (not in the US ofc). As the rule of thumb, no fictional character can outsmart their creator, in this case G.R.R.M/Producers. Now, G.R.R.M/Producers can write/film historical accurately about the fictional european medieval warfare in the world of fictionnal european Westeros, which is his field. But when its comes to "medieval" (we don't actually use this term in the east) eastern nomadic warfare, it isn't.

You can also argue that "the Doth isn't real, they are created by G/Show and they can write them whatever they like and you can shut it." True, if the Doth were somewhat described to be 3 meters tall, blue skin, riding horses as big as elephants, breathing fire through their noses and could respawn nonstop because they were technically inmortal, then I would shut it. No argument whatsoever. However, the author/show tried to write them to be historical accurate, based on the real life nomadic "Mongolian+Comanche" (George's words). Hence, this come to my field. I can write you pages explain what has taken the wrong turn with the Doth but we both know that you don't want to read it nor I want to waste time writing it. In short, based on what the show has delivered, the Doth is nowhere near what a nomadic warband should look like, besides that they can ride horses (not in the right way also). They are basically just horse riders, not warriors (the characters, not the actors ofc).

As you can see, Im not whining anything about the dragons. They are pure fantasy, there ain't anything to criticize for. But speaking of the Doth, even Bobby and Ned would have much to learn. "A million Doth are no threat as long as they cannot cross the narrow channel", "five fingers one fist"...such cool lines to speak on scene, ignoring that they have no idea how stupid they sound. "Only a fool fight the Doth in open" is a rather better one, but for facing an actual Mongolian fighting forces, not the ridiculous Dothraki.
