Tiger Killers

The German Tiger tank gained significant renown during the Second World War and remains a popular topic in discussions of this period even today. While some modern interpretations paint the Tiger as a semi-mythical wonder weapon, its contemporary evaluations are much more reserved. Let’s take a look at the conclusions drawn by British specialists who studied this tank and the measures they devised to fight it.

Clash of heavyweights

The Western Allies first encountered the Tiger tank around the same time it appeared on the Eastern Front. A successful offensive in North Africa forced Hitler to take severe measures, including deploying his latest weapon. The 501st Heavy Tank Battalion began its landing at Bizerta, Tunisia, on November 23rd, 1942. It first saw battle on December 1st, but the scale of combat was limited. It’s not surprising that Allied intelligence obtained relatively little information on this tank around this time. An article in the Tactical and Technical Trends magazine dated February 11th describes a new enemy heavy tank weighing on the order of 50 tons, equipped with an 88 mm gun, and with 80 or 100 mm of armour. This tank was called Mark VI or Pz.Kw.6.

Agents report (still need to be confirmed) that the Germans are producing B-4 tankettes that are controlled by radio and are conducting training on their use.

The tank is loaded with 300 kg of explosives and has several smoke emitting devices. It is designed for destruction of bunkers, making passages through obstacles, and clearing minefields.

On orders of the Deputy People's Commissar of Defense, Army Commander 1st Class comrade Kulik, I send you a copy of the act on the inspection of combat and training in the 1st Army Group for your inspection and execution of necessary measures.

Deputy Chief of the 1st Department,

1. Permanent units

[...]

Armoured units:

The 7th, 8th, and 9th Armoured Brigades are essentially armoured cavalry, more suitable for guarding borders and internal security. They did not train to fight alongside infantry and don't know how to do this. These units played a big role in the initial stages, but took heavy losses. The arrival of poorly trained reinforcements weakened them, they need to train and re-equip.

Ever-Changing Tank Nomenclature

One of the topics that resurfaces in arguments about armoured vehicles is classification. It wouldn’t be so bad if people far from the science of armoured vehicles made mistakes, but quite notable historians also throw fuel on the fire. The T-28 is one of the most misunderstood vehicles. There is a certain group of people who draw modernisations onto the T-28 that would allegedly make it a suitable replacement for the T-34. After all, both have a 76 mm gun, similar weight, two tracks, basically the same thing! The fact that the T-34 was built to replace the BT doesn’t bother them, neither does the fact that it was the SMK that was first supposed to replace the T-28 and then the KV. The T-28 tank was included in heavy tank brigades. This seems like a very strange fact if one is not familiar with the Red Army’s system of classifications. Similar mistakes are made regarding tanks of other nations. For instance, the Panther is often called a heavy tank, but it’s enough to look at where these tanks went and what vehicles they replaced. Today we will cover the Soviet tank classifications, touching foreign vehicles a little for context. Keep in mind that the same names can mean different things in different times.

Polish Tank Destroyer

The growth of tactical-technical requirements is a normal phenomenon for any army in the world. The brass also often doesn't know when to stop, which results in a strange metamorphosis. This happened to the tankette class of vehicles. Initially, the concept was something akin a mobile machine gun nest: a machine gun with a shield, engine, and tracks. Early tankettes were one-man vehicles, but experiments in the early 1920s showed that you need at least two crewmen. The Carden-Loyd Mk.VI is a classic example of this concept. Nevertheless, many nations quickly started treating it as a tank, albeit a small one. Requirements for these tankettes grew until they were more suited to tanks, and so the tankette withered away.

Video: 6-pounder and 57 mm M1 Gun in the USSR

Both British made 6-pounders and American made 57 mm M1 guns were shipped to the USSR in various forms, but one was received much better than the other. I talk about why in my latest video. Huge thanks to Major (Ret.) Michael Calnan, the Swords and Plowshares Museum, and the 1st Canadian Parachute Battalion and 191st Rifle Division reenactment groups for the footage used in this video.

The Main Soviet Pre-War Tank

There were many cases in tank building history where development programs were restarted almost from scratch. This happened with Soviet tank development at the end of the 1920s and start of the 1930s. By the end of the 20s, the USSR composed requirements for armoured vehicles and created their own tanks. The first such vehicle was the T-18 (MS-1) small support tank accepted into service on July 6th, 1927. This tank was a grand achievement for Soviet industry. It was a very modern tank for the mid-20s and, most importantly, it was mass produced. It was a challenge, but production was fully set up by 1930. The problem was that the tank was already obsolete by then. The Red Army fully understood this. The first solution was to modernise the T-18, but the idea of finding a suitable replacement abroad was also raised.

Artillery vs Fortifications

 "To the Military Council of the 16th Army

1. Experimental trials using an anti-tank rifle, 45 mm gun, and 76 mm gun were performed against an earth and timber bunker on July 31st, 1942.

The size of the bunker was 5.5 by 5.5, the thickness of the walls was 1.4 meters, formed by two log frames. The space in between was filled with earth and logs. 

Results of firing from 300 meters:

  1. 76 mm regimental gun:
    1. HE grenade fused for explosive effect: the outer log frame is destroyed with one grenade. 5-7 direct hits are needed for complete destruction.
    2. Shrapnel with impact fuse: wall of the bunker is penetrated fully, shell explodes inside the bunker.
  2. 45 mm gun AP shell: penetrates both the front and rear walls of the bunker.
  3. Anti-tank rifle: at 100-200 meters the bullet penetrates one wall of the bunker. The bullet maintains enough energy to kill.
Conclusions: to improve the effectiveness of earth and timber bunkers, the thickness of the walls must be increased. Conduct additional trials.

Via Alexey Isayev

This data is interesting on its own, but it's also interesting to compare to deliveries of foreign tanks. The first Matilda and Valentine tanks began arriving during the Battle for Moscow and were thrown into battle with little preparation. As you can see in the above table, once the situation stabilized a little bit it took some time before new units with British tanks could be properly outfitted. Large deployments of Matildas and Valentines only take place in April, four months after deliveries began.

A similar picture can be seen with American tanks. The first shipments arrived in January of 1942 and we start seeing a small number of these tanks on the battlefield in April-May, 4-5 months later. Once the pipeline was set up, it was not as hard to deploy new tanks. A bump shipments that came in May hits the front lines in June. A lot of tanks were tied up in delivery by the end of the year: 3875 foreign tanks were delivered to the USSR in 1941-1942, but only 2530 were actually fielded before the end of 1942.

You can see the same pattern with Soviet tanks. Evacuation of factory #183, the USSR's largest producer of the T-34 tank, began in September of 1941. The factory began to set up in the Urals in December-January, and by May of 1941 you see a spike in deliveries of T-34 tanks. Similarly, production of the T-70 was authorized in March of 1942 and we see these tanks begin to arrive on the front lines in July.
