| Notes | The 100mm BS-3 was the most powerful anti-tank gun produced by the Soviets in world war two. It was powerful enough to combat even the German panthers and tigers at a good range and was capable of being used in the field artillery role. The weapon itself appeared late in the war and by 1944 around 591 and only 185 were in service in January 1945. It was issued to artillery in tank armies and at corps level. |
