They do have those limitation, but the thing is unlike in the past modern radars have a lot better detection of the noise near the ground. And also multiple radar in high position and different locations makes it very hard to do anything without detection. And cruiser missiles as said before are easy targets for thor and panser systems. Systems as s400 and s300 are mainly used for elimination plane threats.
It's actually a huge problem for turkey to do anything, because a huge part of its territory is under surveillance both from sea and ground, and the anti air system go very deep in its territory. Not only would they have huge casualties trying to go through the air defense, they would have problems on the ground itself as they are in range of multiple ballistic and also cruise missiles from fleets, in fact their territory is in a way flanked making any move for them extremely hard now and expensive. So its not easy to do at all as you assume here or with low casualties.
Surveillance? Lol. Russia can be fighting in Syria but they wont be attacking within Turkish borders. That would end Putin's autocracy real quick, so I figure any accidental violations would be dealt with in crisis phone line to Brussels and Washington, past the problem member of the alliance.
Those same radars are also themselves "easy" targets(easier than what they try to track) because they need to radiate to operate, and they rely on yet more radiating missile defenses for their own protection. Anyone blinking is seen further than they themselves see. Why do you assume unreal capabilities from of just a couple of launchers, no matter what they are?
And those long range missiles arent very maneuverable. The short ranged ones too don't have a higher load factor than Western missiles that have scored a Pk of about 50% only, and against much lower tech opponents to boot. The Pk has been only high against friendly helicopters. An S300/400 launcher vehicle only has 4 tubes, the potential of kills one can shoot before its dead is rather low, if cost effective. Pk is a thing and saturation works because defensive systems can only track and shoot so many targets at once.
No system is perfect, planes and missiles get through. Turkey and Saudis will have massive superiority in numbers if they decide to move in, it likely wont be even a cost effective to trade whatever Russia has in Syria away in combat unless the Turks screw up(which they shouldn't as a NATO member). Similarly, those A2/AD systems are operated by people too and thing.
Made in Russia plaque and marketing speeches dont make stuff magic.
Sorry if turkey attacks russian forces , be sure that they will be a retaliation on the turkey itself to limit its capabilities to continue the invasion. Phone call does not help when you go and start invading other country where your forces are in. You are here talking about turkey and saudi invading syria, than russia from main land and iran will join also in the mix. So turkey will be mostly fucked, including most of the world as it will be very close to world war 3. So little more though put in this and what will result in it would be good. I know that you want to make it so that if turkey attacks syria and russian forces nothing will happen and they cna do it easy, but that is very illogical to think like that.
Its not exactly a couple of launchers, but it includes fleet, russian ground air defense that is among the most advanced systems at the moment, the aviation, the syrian air defense, the additional russia support from the black sea. It will not work as you say because they would not be fighting only ground air defenses. Less looking at individual systems, and more looking at the system as a whole.
Normally that its operated by people and there are mistakes, but that counts on both ends, and is turkey in nato or not doesnt make it somewhat magical.
Yes no system is perfect, they will have superiority in syria at the moment they move if they move with full force and overrun them (thats the only way they can do it anyway), , but than will be in big problem when the same happens to their territories.
Made in russian doesnt make things magical, but little more logic and looking at the position of turkey and the system placed in syria makes it a lot hard thing to do. There is a reason why russian air defense is considered one of the best in the world.
Anyway I think its enough throwing around wild assumption of can turkey invade syria what casualties it will have and how would they go through after russian and iran response, and let's stay on topic. I think there is similar thread where people talk about fictional wars and who will win or what not, but I am not exactly interested in continuing those conversation or nor am here for that type of conversation of us trowing around wild assumption what will happen and similar, as this thread is actually not about it.
