British saying the Iranian drones flying way better than in the 12 days war, and way harder to intercept them.Most of the tech is definitely coming from China and Russia but not in System but in components for them to built their own system. Intelligence is more difficult, my guess the Russians are giving a lot of support finding US assets but is difficult to know because the Iranians, surprise, surprise have a extensive network of intelligence over the Middle East probably reaching Israel.
Probable Russian training of the operators in Ukriane.
Possibly the Iranians had chances to conduct strikes with they modified drones in Ukraine, in real, jammed enviroment ,against the same missile defences that they encounter in the Persian gulf.
