I have multiple issues with GÜRZ. First of all it goes against land forces doctrine:
Land forces wants to spread out expensive equipment as much as possible to different vehicles. In tbe case one fails, is hit or has any other trouble like engine trouble or is stuck in mud whatever, the rest should not be useless. That's why Korkut, Hisar etc have radar separate and multiple platforms for launch or firing, with redundancies. Furthermore, it is taxing on personnel to handle too many equipment and jobs at once, instead they want every personnel focused on one task.
GÜRZ is instead like a land ship, it's big, expensive an has everything at once. If one is hit or lost, you lose multiple capabilities, and the cost would be severe as well. You lose radars, jammer, cannon, both missile systems...
Another big flaw is the fact that missiles are connected to turret and pointed in the same direction together. If multiple threats were to engage from different directions you would be unable to fire at all of them at once despite having separate systems for all. If you knew enemy could come from a limited area it could still work but otherwise you would be easily taken out by multiple small drones. So I think they should at least separate the hisar / bozdoğan launchers to a different position. I think going from this idea, you could add sungur or aesa radar to existing korkut systems instead as an upgrade, and have hisar and jammers / laser as separate vehicle. Otherwise to use Gürz effectively, you would need 2-3 of them at once.
