That is precisely why the Empire Army invested heavily in developing a field air defense system centered around small-caliber high-altitude guns.
This is the "FP-95A" self-propelled high-altitude gun.
This self-propelled high-altitude gun, which was almost simultaneously commissioned with the ZT-99A, is the Empire Army's masterpiece after nearly twenty years of effort.
In fact, the FP-95A can be seen as a modernized version of the "Shilkha."
In the later stages of the Boi War, the Empire Army seized several almost intact "Shilkha" self-propelled high-altitude guns and conducted tests on them.
By the standards of the time, the "Shilkha" was considered a very advanced field air defense system.
Of course, there were many problems as well.
The most prominent issue was the lack of a fire control system, leading to poor independent combat capability, and it struggled against high-speed targets.
Furthermore, the power of the 23-millimeter ammunition was clearly inadequate.
