Afaik Russian air defense systems are geared towards intercepting fast moving ballistic objects and not slow propeller driven aircraft flying close to the ground hence why Ukranian drone strikes are so difficult for them to intercept. You need air defense systems that are geared towards that like the Gepard and NASAMS and not Patroits.
