Facing a shortage of armoured vehicles of every kind, Canada purchased worn out and obsolete M1917 Light Tanks from the US at scrap value. These tanks were worth little more than scrap. |

45 mm APCR Penetration
"To the Chair of the State Committee of Defense, comrade I.V. Stalin
We present the main results of proving grounds trials of 45 mm subcaliber armour piercing shot designed by Military Engineer 1st Class comrade Burmistrov.
The shot with heavy and hard tungsten alloy shows the best results. This shot satisfies the requirement of penetrating at least 60 mm of armour with the resistance coefficient of at least 2400 at an angle of 30 degrees at a range of 300-500 meters. They considerably increase the power of the 45 mm model 1932/37 anti-tank gun.

Baby IS-3
The Second World War was a catalyst for the creation of many armoured vehicles, including heavy tanks. These vehicles were quite rare at the start of the war, but this changed radically in 1941-42. The Red Army was the most heavily invested in heavy tanks. At first, Soviet heavy tanks followed the classic path of gaining more and more weight, as a result of which the KV-1 became overloaded. The need for mobility led to the KV-13 and KV-1S. The result of this new branch of development was the IS-1 (IS-85) tank, which was quickly replaced with the IS-2 (IS-122). The tank combined powerful armament with sufficient mobility and high levels of protection. Nevertheless, work on modernizing the IS-2 began in the spring of 1944.

The Wehrmacht's Unplanned Workhorse
How the Pz.Kpfw.IV became Germany's most numerous and longest serving tank.
There are many cases in worldwide tank building where not everything went according to plan. Even the legendary T-34 was supposed to leave the stage in 1941 in favour of the T-34M. Only the start of the war saved it from replacement. A similar thing happened to the Medium Tank M4. It was supposed to be replaced in 1943, but the replacements didn't turn out well. This happened to every long-serving tank, and the Germans were no exception.
The Pz.Kpfw.IV Ausf.C was the most common German medium tank at the start of the war. |

Heavy Trophies from Leningrad
There are plenty of armoured vehicles that had an impact on tank building worldwide. This list includes German vehicles, especially the Tiger tank. At the moment of its appearance, it was the best protected and most heavily armed tank in its weight class. Even though the effectiveness of Tiger crews is often exaggerated, this was indeed a very dangerous enemy, especially from 1943 to the spring of 1944. Tanks all over the world evolved to deal with Tigers.

Heavy Without Alternatives
One can often encounter brainstorms about how individual vehicles or even entire tank building schools ought to have evolved. Most of these brainstorms are done by people that are far removed from the field of history, but sometimes even notorious historians take part in this exercise. Among Soviet tanks, the T-28 is a popular character in alternative history. Modern improvements to this tank know no bounds, but the fact that the T-28 was replaced by the KV-1 and not the T-34 is often ignored, as is the fact that a replacement for the T-28 by the name of T-29 already existed.

Video: Is the KV-6 Real?
The KV-6 Behemoth is one of the most infamous fake tanks, but is there a kernel of truth inside the fiction? I take a look at the history of the KV-6 tank in my latest video.
