Ukrainian units began to widely use on the line of contact outdated KS-19 100 mm anti-aircraft guns, developed in 1947 and intended to fight air targets.
In all likelihood, the Ukrainian army has serious problems not only with ammunition for Western-style artillery systems, but also with firearms. Nothing more than this can explain the use of outdated anti-aircraft guns.
In addition, as noted by military experts, entire artillery batteries from KS-19 guns are being formed in the ranks of the Ukrainian Armed Forces. They plan to use them exclusively to destroy ground targets, since there are simply no air targets that KS-19 guns can fight in the Russian army.
I must say that there is not even a smell of bicycle invention here. Anti-aircraft guns were fired directly to fight tanks during the Great Patriotic War.
But then in the Red Army there was a serious shortage of anti-tank weapons. The current Ukrainian armed forces do not have such a deficit. Even at the very beginning of the special military operation of the Russian Federation, the West supplied them with anti-tank weapons.
The use of outdated anti-aircraft guns against ground targets testifies, first of all, to the lack of modern artillery systems. And this, in turn, is a clear proof of the effectiveness of the counter-battery work of the Russian gunners. In addition, one should not forget about the successful use of Lancet kamikaze drones by Russian units. It is these drones that have recently turned into real Western-style artillery fighters.
According to a source these are being deployed as antipersonnel weapons and not AAA.
