World of Tanks History Section: USSR's "Foreign" Medals

The Red Army drove the war off Soviet land by the end of 1944. Ahead lay countries that Germany conquered, its allies, and of course, the "heart of the beast", Germany itself. Seven special medals mark the war path of Soviet soldiers and officers beyond the borders of the USSR. The Technical Committee of the Chief Intendant Directorate of the Red Army started working on them on April 19th, 1944. On June 9th, these medals were approved by an order from the Presidium of the Supreme Soviet.

Despite their great significance, the medals were laconic. On the front, simple words: "for liberation" or "for capture". On the back, the date of the event and a small five-pointed star.

So which European cities were immortalized in brass in these seven "foreign" medals?

For the Liberation of Belgrade

In late September of 1944, Yugoslavia was occupied by Army Group F, the 2nd Tank Army, and Army Group Serbia. Elements of the 2nd and 3rd Ukrainian Fronts, three Bulgarian armies, and units of the People's Liberation Army of Yugoslavia opposed them in the Belgrade Strategic Operation. The goal of this operation was the destruction of the enemy in Yugoslavia and interruption of routes that could allow the enemy to evacuate to Greece.

Before October 10th, the Red Army captured the Great Morava dale, captured the city of Pancevo, defeated the enemy south of Belgrade, and surrounded a large number of German forces south-east of the city. This prolonged the siege of the Yugoslavian capital. Soviet forces only entered Belgrade on October 14th. In six days, the city was completely liberated.

About 70,000 people were awarded the Liberation of Belgrade medal.

For the Liberation of Warsaw

The 1st Belorussian Front reached Warsaw in July of 1944, and tried to take the city straight from the march. The attempt failed. After Operation Bagration, Rokossovskiy's forces did not have the strength.

By January of 1945, the Red Army pulled up its reserves. One of the largest operations of the later war began, the Vistula-Oder Offensive. At this time, the Germans pulled back some forces to the Western Front in order to attack in the Ardennes. The timing was right.

Pushing the enemy back across the Vistula, Soviet forces crossed the river, surrounded the enemy from the west, and began the siege. On January 17th, after fierce battles, Warsaw was cleared of the enemy and came under Red Army control.

As of 1995, about 700,000 people were awarded the Liberation of Warsaw medal.

For the Capture of Budapest

In 1945, Germany had just one ally left in Europe: Hungary. The Budapest Offensive Operation was carried out by the 2nd and 3rd Ukrainian Fronts starting on October 29th, 1944, and lasted almost three months, until February 13th, 1945. The battles in this operation were so fierce that Budapest was nicknamed "Stalingrad on the Danube".

In November-December, the Red Army reached the outer defensive perimeter of the Hungarian capital. An attempt to take the city straight from the march failed, and the Soviet forces spent some time dealing with the enemy north and south of the city in order to encircle the German and Hungarian forces within. This was accomplished by the end of December, even though the enemy attempted three powerful counterattacks. An offer to surrender was presented to the surrounded garrison on December 29th, but the negotiators could not even approach the enemy positions. Both groups were fired upon by machineguns and mortars. Three negotiators were killed.

For four weeks, fierce street battles raged in Budapest. The main role in these battles was played by Soviet assault groups and sappers. Pest, the Eastern part of the city, fell on January 18th. On February 13th, the forces defending Buda surrendered.

About 362,000 people were awarded the Capture of Budapest medal.

For the Capture of Koenigsberg

Koenigsberg was a fortress for all its existence. The Red Army's East Prussia Offensive of 1945 was one of the most difficult and bloody.

The Soviet command only started preparing for the final offensive of Koenigsberg in March of 1945. It was assigned to the forces of the 3rd Belorussian Front and the Zemland army group commanded by I. Bagramyan. The fight for the city began on April 6th.

Before assaulting forces entered Koenigsberg, it was "worked over" by artillery for several days. As with many other cities, assault groups were widely used, small mixed units, most effective in street fighting. The Red Army managed to cut off the Koenigsberg garrison in only two days. A breakout was attempted on April 9th, unsuccessfully. After that, understanding the futility of resistance, the enemy surrendered. The last resistance in the city was extinguished on April 10th.

About 760,000 people were awarded the Capture of Koenigsberg medal.

For the Capture of Vienna

Soon after Budapest, the Germans carried out their last large offensive on the Eastern Front, at Lake Balaton. The operation failed, and the Soviet counterattack made a push for the Austrian capital: Vienna.

The battl for the city started on April 6th. Germans had to be squeezed out of every city block. By April 10th, the garrison was surrounded from three sides, and had only one path to retreat, over the Imperial Bridge. An attempt was made to capture it with marines dropped off by the Danube fleet, but the resistance was too great. The offensive stalled a mere 500 meters from its goal.

The decisive attack started on April 13th. It was so quick that the city was in Red Army hands by noon. What little was left of the garrison left by the bridge.

Over 277,000 people were awarded the Capture of Vienna medal.

For the Capture of Berlin

On April 16th, 1945, elements of the 1st Belorussian Front and the 1st Ukrainian Front began the most important and largest Red Army offensive operation in Europe: the assault on Berlin. It took five days to reach the city. On April 21st, the Red Army was at the outer defensive lines.

The city held until May 2nd. Soviet assault groups cleared it out house by house, block by block. This was a difficult task, considering that any robust house was turned into a fortress and the streets were covered in obstructions, pillboxes, and barricades.

On April 29th, the Soviet forces flew the Banner of Victory over the Reichstag. On the next day, Hitler committed suicide, realizing that help will not come and the Third Reich has come to an end. Berlin fell on the night of May 2nd.

Over 1,100,000 people were awarded the Capture of Berlin medal.

For the Liberation of Prague

Berlin fell, but a fairly strong group of German forces remained in Czechoslovakia. The Prague operation was the last to be carried out by the Red Army in the Great Patriotic War.

When Soviet forces approached Prague, the large German garrison retreated westward. At the same time, an uprising erupted in Prague. As a result, a large enemy force was encircled east of the city.

Soviet forces made a rapid march to Prague on the night of May 8th to May 9th and occupied it on the same day. The Germans surrendered on May 11th, 1945, after a series of powerful attacks and artillery strikes. The last battle of the Great Patriotic War was over.

Approximately 400,000 people were awarded the Liberation of Prague medal.

Order #227 in the 4th Tank Army

"August 14th, 1942

To the deputy People's Commissar of Internal Affairs, Commissar of State Security 3rd class, comrade Abakumov

Despite the overall positive reaction to comrade Stalin's order #227, there were a series of negative and downright anti-Soviet statements made by individual troops and commanders, such as:
  • Red Armyman Katasanov from the 2nd battalion, 22nd Motorized Infantry Brigade said that "There are a lot of orders, but if there is no strength left, you can write as many orders as you want, nothing will help."
  • Red Armyman Shelopayev of the 113rd Tank Brigade's motorized infantry battalion said: "It's nonsense, there were similar orders before, and we still leave cities behind. This order won't help, we'll keep running until the Volga."
  • Red Armyman Andreev from the administrative platoon of the 121st Tank Brigade said: "You can write any order you want for us, we won't do it, same as before. Other orders said that you must fight cowards and panic-mongers up to execution on the spot, but there were no measures taken. It will be the same with this order. It will soon be forgotten."
  • Deputy commander of a tank battalion in the same brigade, Korotayev, said: "Innocent commanders and groups of infantry will suffer from this order, when they panic it's hard to hold them. Good commanders may suffer."
  • Red Armyman Kizshin from the HQ battery of the 18th Infantry Division said: "To battle, so that I might get wounded and go to the hospital for a few months, then the war will be over. The order says not one step back, but the ones that wrote it run first."
Up to 20 such statements were made in the units of the 4th Tank Army. The unit commanders have been informed by NKVD special departments. Despite discussions of comrade Stalin's order with personnel, there were cases of cowardice, sabotage, and dereliction of duty by individual soldiers and commanders. NKVD special departments take measures against cowards and panic-mongers, who sap the resolve of units, throw down their weapons, and flee from the battlefield.

During the aforementioned time period, 24 men were executed. This includes squad commanders in the 414th Infantry Regiment, 18th Infantry Division, Styrkov and Dobrynin, who cowardly ran from the battlefield, abandoning their squads. They were detained by a blocking squad and executed in front of their units on the orders of the special department.

Red Armyman Ogorodnikov from the same regiment shot himself in the left arm. His deed was discovered and he was handed over to a military tribunal.

There were cases where entire operations failed due to cowardice. For instance, during the night between July 31st and August 1st of this year, 176th Tank Brigade left positions without orders, and let the enemy take these valuable heights. An investigation revealed that the HQ chief Major Maksimov was at fault, who was arrested by the special department and is awaiting trial.

The commander of the 6th Battery, 616th Artillery Regiment, 184th Infantry Division, Lieutenant Radbil, did not fulfil the order to support infantry and tanks on July 30th, and when the battery was shelled by the enemy, he said "Anyone who wants to can save the battery, I'm walking away from this"

Based on Order #227, three blocking squads were composed, each of 200 men. These units are armed with rifles, submachineguns, and light machineguns. Members of the special departments command these units. As of August 7th, 1942, 363 men have been detained by these units, of which 93 just escaped encirclement, 146 fell behind their units, 52 lost their units, 12 escaped from enemy captivity, 54 ran from the battlefield, and 2 had questionable wounds.

After careful checking, 187 were sent back to their units, 43 to a reinforcements base, 73 to NKVD camps, 27 to penalty companies, 2 to medical examination, 6 were arrested, and as mentioned above, 24 were executed.

The military council has been informed of the above.

Selivanovskiy."

Reactive Armour and Edge Effect

Penetration mechanics of even simple steel are complicated enough, but can be somewhat simplified for most uses, such as penetration tables and video game calculations. However, when reactive armour is thrown into the mix, how does one evaluate its increase in protection? How does the edge effect, present in only a small percentage of hits on conventional armour, affect it? An article in the Armoured Journal (Bronetankoviy Vestnik) by A.I. Anisko, S.V. Bodrov, D.A. Rototayev, and A.A. Scinarenko attempts to answer this question.

"Reactive armour is used to protect tanks from HEAT shells. Usually, these are removable containers with thin steel plates, sandwiching an explosive element. In order to place these elements correctly on the hull, one must first consider the protection of the reactive armour when used with the main armour. One methodology counts it as an equivalent thickness added to the main armour in certain conditions of HEAT shells striking the center of the container. Consider the dependence of the protection of the reactive armour and the time of reaction of the HEAT jet and protective plates. When the point of impact is moved from the center to the edge of the plate, the penetrative power of the HEAT shell decreases by 30-60%. However, the contribution of the edge effect to the protection of reactive armour has not been explored. 

A contained with two reactive armour elements were tested. The test was performed by detonating the warhead of a 93 mm AT grenade at an angle of 60 degrees. The warhead was placed to imitate a hit to various parts of the container (fig. 1). The peripheral points were 10-15 mm away from the side of the element."

Fig. 1. Locations of hits to the container.

The following is the data obtained when detonating the warhead, averaged over 5 trials for each point. Remaining penetration is defined as penetration through a plate of medium hardness steel after passing through the reactive armour. Q is defined as the contribution of the reactive armour to protection, obtained by subtracting remaining penetration from penetration through the same steel plate when no reactive armour is present. This table contains both the predicted and experimentally obtained Q.

Point Remaining penetration Q (calculated) Q (experimental)
A 211 266 258
B 37 452 462
C 274 214 225
D 292 179 207
E 86 420 413
F 376 126 123

When hit in the center, the reactive armour has the greatest effectiveness, adding over 450 mm to the thickness of the armour. When hit in the sides, the effectiveness is about half as much, even less when the HEAT jet hits the corners of the plate. This is caused by the various sizes of the plate fragments that interact with the HEAT jet, as well as the number of fragments it is likely to pass through. 

The scientific model is pretty good, as you can see from the small differences between the predicted and observed values of Q. The model predicts that about 25% of the surface area of the reactive armour element will give more than 400 mm of additional protection, about 50% contributes more than 350 mm, and about 75% contributes more than 300 mm to the tank's armour.

The equation that governs this distribution is Q=123.85+3.4x1+3.77x2-0.027x12-0.016x22 and looks like this when plotted.

Lisow Finisher

Remember that battle in the Lisow direction where a battalion of shiny new King Tigers was stomped into the ground? Isayev wrote that the tanks were falsely identified as Panthers, but perhaps not entirely, as this award order suggests.

"Award Order:
  1. Name: Novikov, Vasiliy Ivanovich
  2. Rank: Guards Lieutenant
  3. Position, unit: tank reconnaissance platoon commander, 3rd Tank Battalion, 53rd Guards Fastov Order of the Red Banner, Order of Bogdan Khmelnitskiy Tank Brigade
    is nominated for the title of Hero of the Soviet Union.
  4. Year of birth: 1921
  5. Nationality: Russian
  6. Party affiliation: VKP(b) candidate
  7. Participation in the civil war and subsequent actions in defense of the USSR and Patriotic War: South Front (February 1942-August 1942), North Caucasus Front (August 1942-December 1942), 1st Baltic Front (February 1944-April 1944), 1st Ukrainian Front since June 15th, 1944.
  8. Wounds or concussions in the Patriotic War: wounded on January 19th, 1945
  9. In the Red Army since: October 1940
  10. Recruited by: Pushkin recruitment office, Moscow oblast
  11. Previous awards: Order of the Red Banner, August 1st 1944
Brief and specific description of the heroism or achievements: as a reconnaissance platoon commander, comrade Novikov demonstrated exceptional bravery and heroism in battle for the Socialist Motherland. during action with his battalion from January 12th, 1945 to January 19th, 1945. During this period, he personally destroyed many enemies and enemy vehicles including 4 tanks: 2 Tigers, 1 Panther, and 1 PzIV. With his gun, he killed about 200 German soldiers and officers

Comrade Novikov was the first to cross the German state border, destroying 4 AT guns, 2 field guns, crushed 5 MG nests, and destroyed up to 50 cars with military cargo.

In battles for Radomsk, he was among the first to burst into the city and captured up to 50 enemy soldiers and officers.

He is worthy of the title of Hero of the Soviet Union."

CAMD RF 33-793756-34

Tiger, King Tiger, close enough. The Panther and PzIV may not have been misidentifications, as the Tiger unit was refilled with whatever was available, including Panthers and PzIVs.

"14 January 1945: 3 tanks of the 2./schwere Panzer-Abteilung 501 fight near Kielce. Several Tigers continue fighting in the following days in the big pocket, but all have to be blown up after running out of fuel. Tiger 323 (Oberfeldwebel Schaffer) breaks through a 12-ton bridge and is abandoned. The remnants of the battalion gather at Griinberg (Silesia). In this area, several crews received surplus armored vehicles (2 Panthers, 3 Panzer IVs, 2 Hornisse tank destroyers and several Hetzer tank destroyers from the maintenance facility at Brieg)."

The rest of the heroisms of Lieutenant Novikov are not confirmed in the German diary, as the unit neglects to make any entries until January 21st.

Common Questions: A Matter of Ratios

"We estimated that the offensive will start on January 12th, 1945. The Russian advantage was 11:1 in infantry, 7:1 in tanks, 20:1 in artillery. Evaluating the enemy as a whole, it would not be excessive to count 15 times more forces on land and 20 times more in the air. I do not underestimate the German soldier. He is an excellent warrior, and can be thrown into battle against an enemy with five times the numbers without hesitation. With proper control, due to his brilliant qualities, he negated this numeric advantage and won." - Heinz Guderian, Panzer Leader

In various discussions, this 5 to 1 ratio shows up quite a bit, either as a ratio of casualties or a ratio of required advantage to defeat a German force. Sometimes it is more, sometimes it is less, but 5 being a nice round number it is repeated quite often to illustrate the claim that the Allies only conquered Germany with the might of industry and "human waves", despite superior German technology and soldiers.

However, these claims seldom hold any actual numbers or evidence behind them. Let us briefly explore the feasibility of this claim.

Despite being a much larger country, the Soviet Union did not possess a proportionally larger population. The German census in 1939 counted a population of about 79 million. The Soviet census in 1937 counted about 162 million people. Assuming that both countries could raise similar proportions of fighting men, it becomes quite clear that a 5:1 casualty ratio is simply not possible here, as the Wehrmacht could simply kill literally every single Soviet citizen with ease. Glantz's essay The Soviet-German War 1941-1945: Myths and Realities gives some more numbers:

Date German forces in theater Red Army forces in theater
June 1941 3,117,00 2,680,000
June 1942 2,152,000 5,313,000
July 1943 2,786,400 6,724,000
July 1944 1,562,400 6,425,000
April 1945 1,960,000 6,410,000

As you can see, the estimate was correct. The Red Army never had a 5:1 advantage over the Germans, not even towards the very end. If Guderian's mythical soldiers were capable of taking on a force five times their size, they could have won at any point during the war, and won soundly. 

Ok, maybe the ratio was not as high as 5:1, but common belief still holds that the Wehrmacht dealt horrific losses to the Red Army and lost only when crushed under a mountain of corpses. Glantz also quite clearly illustrates that this is not true. While Soviet military casualties were quite horrible (14.7 million people), German casualties were also staggering: 10,758,000 lost on the Eastern Front. However, Germany did not fight alone. The Axis Minors fought with them, and adding up only Hungary, Italy, Romania, and Finland adds another 1,725,000 casualties to the German side, for a total of 12,483,000, or a ratio of 1.17:1. Quite a slim advantage.

Edit: it appears that many commenters believe that Glantz's numbers do not accurately represent the amount of Red Army forces and were purposefully chosen to minimize the number of troops available. Livejournal user buckina_new compiled a nice chart using Krivosheev's data about the number of men in the Red Army every quarter.


As you can see, the figure is more or less stable at around 6.5 million after the initial mobilization was complete, just like Glantz's data suggests.

World of Tanks History Section: Victorious '45

Soviet tank armies were at their peak in 1945, a powerful fighting instrument. Each unit could contain up to a thousand tanks and SPGs, and that's not including artillery, infantry, wheeled vehicles, and auxiliary units. At the start of the war, it was unthinkable for a tank army to penetrate 500-700 kilometers into enemy defenses in mere days, surrounding and crushing his forces, pursuing those that retreated and not letting them take up favourable positions. At the end of the war, this was reality.

A fist, not a palm

Combat experience taught Soviet armoured forces to fight with more than gun caliber and armour thickness. Reconnaissance, communication, and cooperation became the cornerstones of successful operations. The army joined its spread out fingers into a single mighty fist.

Sufficient time was dedicated to planning each offensive, from two weeks to a month and a half. During this time, details would be covered for each level of forces, from tank armies to battalions. HQ staff worked with enormous amounts of information: maps, aerial photos, city plans, radio intercepts, information obtained from local civilians and prisoners.

Due to increased reliability of vehicles and improved driver skills, it became possible to gather up forces in regions far from the front lines. Tank armies moved out in secrecy, usually at night. Special roads were designated for tank units, use by all other types of forces was forbidden.

When tanks were in position a few tens of kilometers from the front line, officers studied enemy defenses and negotiated cooperation with other types of forces. Tankers, pilots, infantrymen, artillerymen all shared their experience, furthering their understanding of their colleagues. After such discussions, they even recognized each other over the radio.

Tanks approached their starting positions as late as possible, usually when hundreds of thousands of artillery shells were already falling on their enemies. In theory, tank armies were supposed to enter a "clean" breach, retaining their strength for operations in the enemy rear. In reality, it was the tank attack that helped break through enemy defenses.

In the final battles of the Great Patriotic War, tank armies were covered from the air by a large amount of fighters, ground attackers, and bombers. In the summer of 1945, during the war with Japan, the 6th Guards Tank Army even received their own air reconnaissance squadron.

Float like a butterfly, sting like a bee

Towards the end of the war, a lot of attention was dedicated to preparing units that were small in number, but complex in organization. They were composed of tanks, SPGs, submachinegunners on all terrain vehicles, machineguns, mortars, and powerful army level  radios. These groups burst into cities, blocked roads, crushed unsuspecting enemy columns, captured key positions. For instance, in April of 1945, only 20 tanks and SPGs with a company of submachinegunners and air support burst into the center Vienna and held on until the arrival of main forces.

Soviet tanks appeared in the German rear so quickly that the enemy had no time to react, and often confused them for his own. Here, creativity helped. A regular bucket attached to the barrel of a T-34's gun looked a lot like a muzzle brake used on a German tank. While the enemy was confused, precious seconds were gained.

During the start of the war, German tankers provided their propaganda ministry with great amounts of footage and photographs of their lightning fast breakthroughs. In 1945, the situation was reversed. Now, it was the Soviet media that had ample materials. German vehicles, abandoned without fuel or suddenly captured when being loaded off a train, stacks of trophies and endless columns of prisoners. The Soviet people who were waiting for victory had a lot to look at.

Soviet tankers rushed forward, filling up their tanks with captured fuel and continuing on, crushing any resistance.

American M17 AA SPGs became an excellent method of covering tanks in cities. A torrent of bullets from four machineguns swept away the infantry that was trying to fire at tanks. Domestic large caliber DShK machineguns were also valued by tankers.

Power in unity

All types of forces tried to help out each other. Forward observers called in artillery fire from radio-equipped tanks. Artillery covered the flanks of breakthroughs. Aircraft impeded enemies that tried to discover and attack tank columns, delivered fuel, airmen were assigned to ground forces to guide airplanes on target. In return, tankers sent special squads to capture airstrips, where technicians immediately began to work on cleaning up the base for Soviet aircraft.

Berlin barricades, several meters thick, could withstand a hit from a tank shell. Sappers came to the aid of tankers, blowing up barricades with explosive charges or AT mines.

Holding initiative, Soviet forces could restore knocked out tanks left on the battlefield, as well as recover the wounded. Tanks were repaired so quickly that 90% of reinforcements came from repaired tanks, not from factories. Medics returned two thirds of all casualties to the front lines. In these conditions, no wonder weapon the Germans dreamt of could save the Third Reich, nor could their rapidly dwindling tank aces.

In 1945, the Red Army had six tank armies. All of them had the title of Guards, a title not given easily. Soviet tankers earned them in thousands of battles on all fronts from Germany to the Far East. These were the elites of the Red Army, one of the most powerful in the 20th century.

World of Tanks History Section: Tragic '41

Paradoxically, the Red Army fought many wars by the summer of 1941, but none of them serious. Enemies of the USSR in small wars of the 1930s had little in the way of modern tanks, aircraft, and often could not offer significant resistance. All types of forces, including armoured, had a very small percentage of commanders who had experience against a strong and well equipped enemy. Germany invaded the USSR with the idea that it was going to be a breeze, but there's a reason why there's a collection of German memoirs about 1941 called "Wooden Crosses instead of Iron".

Calm before the storm

It would not be proper to say that the Red Army tank forces lived in the past and the commanders had no idea, at least approximately, what the next war would be like. Books and articles written by Soviet military theorists talked about the importance of massed uses of tanks, with mandatory tight cooperation with infantry, motorized infantry, artillery, and aircraft. Armoured forces were not just for penetrating enemy defenses, but for deep operations in the enemy rear, against his headquarters, reserves, and communications. In defensive operations, tanks were supposed to isolate enemy forces that broke through and destroy them with ambushes or counterattacks.

Spain, Khalkin-Gol, and Finland showed that new tanks must be well armoured, well armed, and have reliable communication and supporting vehicles. Factories received many orders from the military for powerful radios, fast tractors, and various armoured transports.

Here is where the bottleneck was. The USSR could not magically produce tens of new factories. No country in the world could. When WWII began in 1939, even Great Britain and the United States ran into problems with supplying their growing armies with modern equipment and vehicles. It took time to mobilize factories for war.

Nobody knew how much time there was. The world was getting ready for a large war that could start in a month or in ten years. This caused problems with technological deficiency, shortage of manpower, and other difficulties of early war.

Weakness in armour

All problems with Soviet armoured forces remorselessly showed themselves in the first battles. 

It was difficult to find the advancing enemy along the enormous fronts. The Germans did not march in an unbroken line, they collected their forces into fists and decided where to strike. Even if scouts could discover these forces, they frequently could not inform their commanders in time. There were too few tanks with sufficiently powerful radios. Due to this problem with communication, commanders could not react in time.

The difficulty in using any armoured unit lies in the fact that you don't need to just transport your tanks. You need to deliver fuel, ammunition, supporting infantry and artillery. There was a catastrophic lack of transport vehicles, and STZ-5 agricultural tractors, the backbone of the support forces, were weak and slow. Two or three such vehicles were required in order to tow one heavy gun or howitzer.

Even if the commander decided to use only tanks, this did not solve his problems. Old vehicles, T-26, T-28, BT, were worn out and prone to breakdowns. New KVs and T-34s suffered from growing pains like unreliable engines and poor visibility. By the start of the war, no instruction manuals have been produced for these vehicles. Considering that most drivers had miserly experience in driving these new heavier and more complicated tanks, it is not difficult to imagine why many were lost due to technical reasons.

Endure, withstand, prepare

At first, the Red Army had to fight by Germany's rules. In these difficult conditions, the Soviet people protected their motherland as well as they could. 

Tanks that were supposed to fight in large groups were separated into small units or even down to individual vehicles, like in Spain. Often, they had to compensate for the rest of the army. Tankers performed reconnaissance, attacked without infantry cover, became the rebar of defensive lines, guarded headquarters. 

Due to a lack of support, Soviet tanks quickly became targets for German AT guns, which were difficult targets to find and suppress. Sadly, the times when KV tanks were invulnerable were long gone. The Germans managed to gather experience in fighting these heavily armoured vehicles.

It happened that tanks penetrated as deep as German headquarters, but tanks alone could not cement that victory. The Germans, with combined forces groups composed of tanks, infantry, and artillery, encircled Soviet forces and deflected their attempts to break out. Any tank that was knocked out was a permanent loss, since the Germans controlled the battlefield.

Taking heavy losses in vehicles, the Red Army moved from mechanized corps to smaller tank and mechanized divisions. Instead of 375 tanks, these divisions had 215. Further restructuring went down to independent battalions and brigades of 53 tanks, in no small part because it was easier to command a smaller unit.

First bricks in the building of victory

Slowly but surely, the tank forces regained their footing after that first punch. The Germans felt this already in the fall of 1941. 

One of the most famous and most successful tank brigades in 1941 was Mikhail Yefremovich Katukov's 4th Tank Brigade. It was fairly well armed: more than half of the tanks were new T-34s and KVs, but most importantly, its tankers received bitter experience in the summer of 1941, and that experience was well learned.

In early October, Katukov's men deflected the attacks of the German 2nd Tank Group at Mtsensk. Tankers of the 4th Brigade carefully performed reconnaissance and coordinated their actions not only with infantry and artillery, but with aviation. Tanks had special defensive lines prepared, and were carefully camouflaged. The result was noticeable: the Germans lost not only tanks at Mtsensk, but AA guns and howitzers, a rarity for the time.

The tone of German reports changed around this time. Guderian, who did not notice new T-34 and KV tanks in the summer, suddenly started complaining about their "complete supremacy", while the German offensive in this sector stalled. For its skilful and courageous actions, Katukov's tank brigade was the first to earn the status of Guards.

The experience earned in 1941 was bought at a high price, but was summarized in orders and instructions, and spread among surviving tankers and new replacements. Victory was still far away. New battles lay ahead.

8,8 cm Pak L/130

Having seen the 88L/100 Pak, might as well take a look at its larger predecessor, the L/130.


Just the barrel of the gun weighs 5300 kilograms, almost as much as a T-60 tank (5.8 tons). To compare, an entire Pak 37 weighs 327 kg in combat. If this thing was built, it was not going to work like a traditional AT gun.


Naturally, such an enormous beast could not be carried around in one piece, or the barrel would deform under its own weight. Here is a drawing of a connection that joined two parts of the barrel. The barrel separated into three parts in total.


1330 m/s, very nice. DeMarre (with the KwK 43 as reference, by German penetration standards) gives this gun 304 mm of penetration.

Brief and specific description of heroism or achievements: Major Rogozin showed exceptional skill when commanding his tank battalion, personal bravery and courage, exceptional force of will and the ability to rationally control himself in the most difficult battles.

When breaching German defenses west of Kostrzyn, Major Rogozin's battalion was one of the first to rush westward. Destroying the enemy's deeply echeloned defenses, his tanks were the first to reach Munchenberg which was covering the approach to the lair of the fascist beast: Berlin. 

The battalion, with no losses of its own, destroyed the following in battles for this city: 8 Panther tanks, up to 4 batteries of artillery, 180 soldiers and officers, captured 87 prisoners, 23 cars with military cargo, 5 functional guns and many small arms.

Continuing his rapid offensive, Major Rogozin's battalion was the first in their brigade to reach the outskirts of Berlin, and started up a street battle in the Frankfurter Gasse street. The Germans dug in a Tiger tank there in order to impede the progress of our tanks and infantry. Comrade Rogozin bravely drove forward and burned up the Tiger in a quick duel. Inspired by their commander's heroism, the tankers and infantrymen bravely moved out and captured the bridge and barricades.

The battalion delivered heavy casualties to the enemy in battles around Frankfurter Gasse, Aleksandr Strasse, and Kostrzyn Platz, capturing many trophies.

The battalion captured the Silesia train station, and with it 100 train cars, 4 locomotives, 2 warehouses with military goods, and 94 soldiers and officers. During these battles, the battalion has negligible casualties: one tank burned up, 3 tanks disabled, 12 men wounded, and 4 men killed.

For skilful command of the battalion, dealing significant damage to the enemy with minimal losses, personal courage and bravery in battle with the German invaders in the streets of the fascist lair, he is worthy of the top government award: the title of Hero of the Soviet Union."
