The opinion of Gaijin is HQ11 has combined radar and launching system on 1 vehicle. Take a example of BUK, it also combined an ESA radar on the launching vehicle, it can continue battling without searching radar. So the additional vehicles should be removed.
The reason why HQ11 called “system” is not because it is a single platform, its a combination as well as the BUK. So remove the additional BUK system’s vehicle seems fair and reasonable due to this opinion
Also, there is TADS/TELAR for China which is not combined in one platform like the HQ16A
At what time? LD2000 is in the system, beside of that data link is not new in China, it can be a set
Also, the enviroment in top tier is another fact, there is no a proper top tier AA for China in serveral Version since the multi vehicle introduced
Oh btw they both 12.7 just top tier BR
Even they add LD2000, still missing an additional vehicle compare with the other multi vehicle systems. There is dedicated radar vehicle in China and can be easily combined into the systems, Gaijin just choose to ignore it
