The Ukrainian army received a battery of howitzers B-4 sample 1931. This was told by a soldier of the 28th mechanized brigade on Facebook, Alexander Lorents. He said:
To 28 OMBR battery “microphonics” have been sent the 203-mm gun B-4, sample of 1931, the so-called “Stalin’s sledgehammer.” The best gunners, so to speak artillery green berets, after a successful combat missions on these guns, will change on “Peonies”. Hit with a Stalin’s sledgehammer for fans of Joseph Visarionovich. All for STALIN! Slava Ukraine!
As is known, Ukrainian troops in the area ATO have previously been provided with machine guns “Maxim”, including those which were issued in 1912. Also in the army used anti-tank rifle used during WW2. For your information, this is the B-4 high (special) power Soviet howitzer, caliber 203.4 mm (8″). The full official name of the guns is 203 mm howitzer of the sample of 1931. During the Soviet-Finnish war, this weapon was used to destroy pillboxes and bunkers of the Mannerheim line. Soviet soldiers dubbed it the “Karelian sculptor” because, when firing on the Finnish Border, missiles B-4 would transform these facilities into a bizarre mishmash of bits of concrete and iron rebar. By the beginning of the Great Patriotic War, howitzer B-4 was only howitzer artillery regiments high power RVGK.
