My dude, they aren't cavemen. If you can manufacture explosives you can figure out how to order and operate a drone from China. They've been successfully operating an insurgency against the most powerful and technologically advanced military in the world for 20 years. Most of their higher ups are from rich Saudi families and a lot of them have western educations.

Knew some people who were stationed in middle east countries.

Generally I wouldn't really trust the opinions of someone who volunteered to serve in the military about how smart someone else is.
