or history A39 Tortoise Heavy Assault Tank
Or a story of fear that had too big eyes
The current war has swept away all existing military theories. The machine gun fire is so strong that it is enough for a hundred meters to stop any attack by the enemy, who, in order to escape the artillery fire, digs trenches in the rear ...
The Armed Forces of the British Empire were the largest foreign user of Sherman tanks. Out of the total production of 49,234 Shermans, a total of 17,181 pieces were delivered to Great Britain (this, of course, includes tanks that were used in units from the British dominions - Canada, Australia and New Zealand - and colonies, or in the Allied, e.g. Polish units).
Soviet test of the resistance of the German heavy machine to artillery weapons that existed at the time.
Wars have accompanied mankind since time immemorial. And they evolve with it. The twentieth century marked an enormous turning point. Man invented the armoured tracked vehicle and used it to sweep away all previous conventions of warfare. Let us now go back to the very beginning of it all and, step by step, trace the development of armoured vehicles in the world and in Czechoslovakia.
"Fearful," Colonel General Heinz Guderian, commander of the 2nd Panzer Army.
"We didn't have anything like that," Major General FW Mellenthin, Chief of Staff of the XLVIII. Tank Corps.
"The best tank in the world", Field Marshal Ewald von Kleist, 1st Tank Army.
"This tank adversely affected the morale of the German infantry," General G. Blumentritt.
Ever since Simms's Millitary Scout vehicle, designers and military strategists have toyed with the idea of an armored mobile infantryman or a moving motor-driven machine gun nest.
When she visited the Chalepsky Commission in 1930 to buy tanks or license their production in Great Britain, she also encountered prototypes of the A6 Vickers tank, then a "fashionable" multi-tower type. The British side was not inclined to sell this vehicle and further negotiations were not successful. Since the commission always had its eyes on the stopwatch and cameras and gauges always on the lookout, it was decided to "develop" its own type of three-tower medium, in the then terminology of the maneuvering tank, after returning to the USSR.
As with several types of Soviet tanks, the history of this vehicle began with a visit to the Chalep Commission in Great Britain in 1930. The commission members were interested in, among others, the five-tower, thirty-two-ton Vickers A1E1 Independent from 1926, made in a single copy. When it became clear that the structural and production complex tank TG, developed hand in hand by a Soviet-German group of engineers led by E. Grotte, the Soviet industrial complex in the series simply could not produce, the Soviet part of the group of engineers was transferred to work on a heavy tank project.
During the Second World War (especially after gaining the initiative in its second half), following the combat experience and the introduction of new technology on the enemy's side, the Soviet leadership, together with individual design offices, tried to improve their combat technology in various categories. In the category of medium tanks, where the number of manufactured pieces reigned the T-34 tank, specifications were also set, which defined the new requirements for this tank. Thus, the specifications of the T-43 and T-44 (which serial machines still intervened in combat in limited quantities) and finally the T-54 were created.
In the following lines I want to present some - perhaps interesting - data on the engines of medium and heavy tanks from II. World wars. Unfortunately, the whole topic of tank engines is so extensive, and at the same time there are so few usable materials for it, that its exhaustive elaboration is practically impossible in our country. Unfortunately, the data published by various authors are often so contradictory that it is difficult to assess their credibility, so it is possible to reject the correct data and use the wrong one. irregularities (certainly to be found). Of course, I welcome any additional information. However, all possible errors and inaccuracies fall only on the author's head.
Natural uranium ( 92 U) has three isotopes, with uranium 238 predominating:
234 U - about 0.006%;
235 U -> 0.7% (reported 0.71 or 0.72%);
238 U - approx. 99.28%.

Recently, information has emerged about the renewal of the Czech modernization program T-72, which took place in the late 90's. After that, 35 tanks for the Czech Army, which received the designation T-72M4 CZ, were modernized under this program by 2006, and the program was stopped for financial reasons. Now the Czech Republic is considering modernizing several hundred vehicles for its army and possibly for export.
