The Russian Defense Ministry has now released an undated video of the world’s most powerful guns hitting Ukrainian targets. Video shows modernized 2S7M Malka 203mm action. The video did not mention the location of the shootings. The 2S7 howitzer combines a 203 mm 2A44 gun with a tracked chassis with all-welded steel armor. The design came from the Kirov factory in the 1960s and entered service with the Soviet Army in 1976. Russia used this gun twice during the war in Ukraine. Watch this video for more details.
