The Soviet T-28 was among the world’s first medium tanks. The prototype was completed in 1931 and production began in late 1932. It was an infantry-support tank intended to break through fortified defences. The T-28 was designed to complement the heavier T-35, with which it shared many components. The type would not have that much success in combat, but it played an important role as a development project for the Soviet designers. A series of new ideas and solutions were tried out on the T-28 and were later incorporated in future models.
Design history
The T-28 was in many ways similar to the British Vickers A1E1 Independent tank. This tank greatly influenced tank design in the period between the wars, although only one prototype was manufactured in 1926. The Kirov Factory in Leningrad began manufacturing a tank, which was based on the British Independent in 1932. The T-28 tank was officially approved on August 11, 1933. The T-28 had one large turret with a 76.2mm gun and two smaller turrets with 7.62mm machine guns. A total of 503 T-28 tanks were manufactured over a period of 8 years from 1933 to 1941.
Combat history
The T-28 was deployed during the Invasion of Poland and the Winter War against Finland. During the initial stages of the Winter War, the tank was used in direct fire missions against Finnish pillboxes. In the course of these operations it was found that the armour was inadequate and programs were initiated to upgrade it. Frontal plates were upgraded from 50 mm to 80 mm and side and rear plates to 40 mm thickness. With this up-armoured version the Red Army broke through the main Finnish defensive fortification, the vaunted Mannerheim Line.

Another explanation is that the high profile of the tank resembled the old west stagecoaches of the United States.Finns captured two T-28s during the Winter War and five in Continuation War, for a total of 7 vehicles.
The Soviets had 411 T-28 tanks when the Germans invaded the Soviet Union in June 1941. Most T-28s were lost during the first two months of the invasion, many of them abandoned after mechanical breakdown. Some T-28s took part in the 1941 winter defence of Leningrad and Moscow, but after late 1941, they were rare in Red Army service; a few were operated by enemy forces.
Today three T-28s remain, two in Finland and one in Moscow. One restored T-28 is on display in Finnish field camouflage in the Parola Tank Museum, Finland.
Assessment Although the T-28 was rightly considered ineffective by 1941, it is worth remembering that when the Red Army was fielding the first T-28s in 1933, the French Army was still largely equipped with the FT-17, and the Reichswehr had no tanks at all. No army had a series-production medium tank comparable to the T-28 for several years.
The T-28 had a number of advanced features for the time, including radio (in all tanks) and anti-aircraft machine-gun mounts. Just before the Second World War, many received armor upgrades, bringing its protection on par with the early PzKpfw IV, although its suspension and layout were outdated.[5]
The T-28 had significant flaws. The plunger-spring type suspension was poor, but many of the better suspension designs used in World War II tanks had not yet been developed. The engine and transmission were troublesome. Worst of all, the design was not flexible. Although the T-28 and early PzKpfw IV were comparable in armour and firepower, the sound basic design of the PzKpfw IV allowed it to be significantly upgraded, while the T-28 was a poor basis for improvement.
Unfortunately for the Red Army, by the time the T-28 saw combat in 1939, events had overtaken it. The 1930s saw the development of the first reliable high-speed suspensions, the first purpose-designed antitank guns, and a gradual increase in the firepower of tanks. The Spanish Civil War showed that infantry units with small, towed anti-tank guns could defeat most contemporary tanks, and made the under-armoured tanks from the early 1930s particularly vulnerable.
Despite heavy losses, in the Winter War the Red Army’s 20th Tank Brigade, equipped with T-28s, fulfilled its mission to break the defensive Mannerheim Line. As an infantry-support tank, designed to support infantry in breakthrough operations, the T-28 in general was successful for an early 1930s design.
Variants
T-28 Model 1934 or T-28A — main production model with the same machinegun turrets, and similar main turret as the T-35 heavy tank and Model 27/32 76.2mm gun.
T-28 Model 1938 or T-28B — version with improved L-10 76.2 mm gun (from 16.5 calibres to 26 calibres), improved gun stabilization system and improved Model M-17L engine.
T-28E or T-28C — 1940 addition of appliqué armour in response to poor performance in Finland. Total front armour was increased to 80 mm, weight to 32 t, and road speed dropped to 23 km/h
T-28 Model 1940 — the final batch of about twelve tanks had the same conical turret as late-production T-35 tanks.

The lion (Panthera leo) is one of the four big cats in the genus Panthera, and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight,[4] it is the second-largest living cat after the tiger. Wild lions currently exist in Sub-Saharan Africa and in Asia with an endangered remnant population in Gir Forest National Park in India, having disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru.[5] The lion is a vulnerable species, having seen a possibly irreversible population decline of thirty to fifty percent over the past two decades in its African range.[2] Lion populations are untenable outside designated reserves and national parks. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Within Africa, the West African lion population is particularly endangered.
