A serious question in Bali about the electronic linkage in one system of control, command and guidance of air defense systems used by Pakistan .. It is known that the Pakistani army uses several radars and air defense systems, whether from America, Russia, China, France, Sweden or other countries. How are all these systems connected? Can you connect them within one system ?! Or is coordination between them such as the Egyptian way through intercom and telephone ?! Isn't this kind of connection dangerous to aircraft and friendly fighter jets? Just like in Yemen when the UAE Pantsir S1 clashed with a Saudi UH-60 Black Hawk! That incident led to the death of 11 officers of the Saudi forces! I hope that the answer will be supported by pictures, sources and directories, and thanks in advance to all ..
