The Russian Defense Ministry has shared video footage of Russian artillery hammering enemy positions with high-explosive (HE) shells from cover during the special military operation in Ukraine.
The clip posted by the military shows servicemen firing MT-12 Rapira towed guns (also known as 2А29 or Т-12А).
The MT-12 is a classic Soviet anti-tank gun, still very effective as a light artillery piece, given that it has a relatively large 100mm caliber for its weight.
