Yes, let's embody the literal God of the Islam. Let's name a BrigGen after some farmer with goats? I am not sure whether this is like an actual suggestion lol. Like Theos already said, you're proposing some meme ranksystem or some kind while saying people want to be a part of the actual Taliban army structure? If anything, it would make sense to use a system that has Arabic (or whatever language they use) ranks as they do in real life.
Goat Herder as BrigGen? Allah as leader of the Taliban? I mean, they believe in a God, yes, but letting a person roleplay as Allah? Bad idea if you ask me. You're only suggesting political ranks, which hold no place in the current Taliban structure anyways. In real life, Taliban doesn't have a Sultan nor a Prince or some sorts.
