Far East Variety

As I've written before, the tank fleet of the Far East Front was rather heterogeneous. Large amounts of T-26 and BT tanks were preserved there, since there was little for them to do in Europe. When the war moved over to the Far East, these tanks were ready to spring into action.

Conclusions:
  1. The army's units are fully equipped with armoured vehicles.
  2. Instead of the authorized amounts of T-34 tanks, the tank brigades are half full of obsolete T-26 and BT-7 light tanks.
  3. The 48th Independent Tank Regiment's KV tanks require medium repairs and cannot participate in the operation."
Interestingly enough, at least one of these BT-7 tanks was a refurbished tank equipped with applique armour.

Karabin wz. 35: Secret Weapon of Rzeczpospolita

One of the most popular themes in anti-tank defenses during the interbellum period was the development of anti-tank rifles. Designers had several approaches to this issue. One was the use of "cannon" calibers of 20 mm, or even 24 mm, with a relatively heavy bullet and a lower muzzle velocity. The other approach was to increase the muzzle velocity of a regular 6-8 mm rifle bullet. The wz. 35 anti-tank rifle was a product of the second approach.

BT Artillery Tanks

"Report on experimental works for January-April of 1937 at plant 191 (factory #183)
...
4. Trials of BT-7 vehicles with KT-26 turrets

Trials of BT-7 tanks with 76 mm guns began. The vehicle's weight increased to 13,800 kg. The first trials showed that 12 springs installed on the main friction clutch is not enough to provide reliable operation. The clutch slips on grades, turns in sand and on soft earth. Currently, the amount of springs is being increased to 16, after which trials will continue.
...
6. Trials of BT-8 vehicles

Two vehicles are currently undergoing trials: one with a 45 mm gun, one with the KT-26 turret for the 76 mm gun. The BT-8 with a 45 mm gun turret travelled 450 km during trials since December of 1936, and had three cases where the fan motor broke. The motor broke and the vehicle is awaiting a new engine.

The BT-8 with a 76 mm gun turret travelled for 728 km and had two cases of fan breakage. The motor is out of action. Both vehicles had experimental motors that did not go through quality control. 

Presently, a new engine that has been approved by quality control and the military representative has been received and is being installed on the BT-8. During installation it was discovered that the crankcase of the engine is leaking oil.

Cheating at Statistics: Claims at Klepenino

A common excuse for German inflation of claims is that the battlefield is left to their enemy, so there is no possible way to count how many enemy tanks were lost. However, even on the defensive, the Germans seem to manage to greatly overestimate the damage dealt to the enemy. According to the the 1972 edition of the Deutsches Soldatenjahrbuch, the 561st Tank Destroyer Battalion destroyed 34 Soviet tanks, "nearly all heavy and super-heavy" during their defense of Klepenino between January 29th and February 8th of 1942. Let's take a look at what was happening in the area and what these "super-heavy tanks" really were.

"Dachshund" for Assault Artillery

The success of the Semovente M40 da 75/18 caused Italian command to order "the same one, but bigger". The result of that request was the Semovente da 105/25, which was nicknamed Basotto (Dachshund).

In April of 1942, soon after the combat debut of the Semovente M40 da 75/18 in North Africa, the Inspectorate of Artillery of the Royal Italian Army ordered the creation of a more powerful SPG, armed with a 105 mm gun. In response, the Odero-Terni-Orlando conglomerate (commonly known as OTO) proposed the creation of an SPG on the P26/40 tank platform. This vehicle was classified as a heavy tank in Italy, but was in reality a medium tank, as it weighed 26 tons. The chassis could allow for a well protected and mobile SPG, but there was an issue: the P26/40 was still in the prototype stage, and there was no concrete timeline for when it would go into production. Using the chassis of the best Italian tank to build secondary vehicles was also considered a waste.
