Then I guess china wasted it's time with FN-6/ FN-16. What were they thinking? S-200-400 haven't been able to sanitize the syrian skies from drones many times and chinese systems seem based on those designs so I guess they can't deal with it either? You have to look at the system for what it is and not make silly statements like "there shouldn't be unexpected directions". There shouldn't be drone swarms but that's life isn't it? There is no indication stinger was present at the time if this attack and failed to do it's job. The times patriot is oriented in the right direction it has intercepted many targets in combat. Those are the main facts here. It sounds like you are saying that stinger can shoot down drones, but that it's not used by the saudis so its not good? Using such simplistic logic yj-27 radar is in syria but f-22/35s have been flying and bombing in syria so the chinese radar must be garbage? See how silly these statements are without context?I didn’t say they can’t shoot down drones and missiles don’t put words in my mouth. Drone or missile attacks can come from any direction there shouldn't be any unexpected directions. Facts speak for themselves if they are not used then they are not used for a good reason.
