The Shilka is a light anti-aircraft unit in service of the Russian Federation. It is currently only available through the Russian Armour Reserves General Power.
Introduced in the early 1960s, the ZSU-23-4, named after its armament of four 23mm anti-aircraft cannons and more commonly known as the Shilka, has been refurbished in a last ditch effort to maximize the combat capabilities of Russia's Tank Reserves alongside the Rhino Tank and the BRDM-2.
This vehicle still has its own effectiveness, however, not powerful as the Tunguska in terms of firepower. But it can be useful at your disposal, with its autocannon, it can take down helicopters and infantry with ease especially en masse.
With its cannon, somehow it is effective against structures though it is slightly, unlike it's counterpart. When in altogether, will surely bring down the structures quite faster.
