As we know, Germany in the beginning of the Second world war there were two types of medium tanks: Pz.HI and Pz.IV. Both cars were created in the mid 1930-ies very close to the reference, which led to the creation of two almost identical in weight, size and booking, but differing in armament and in the end — a completely different construction machines. It is difficult to give an explanation. For example, a base weight was 15 and 18 t, respectively. Significant differences were only armed with one machine had to carry a 37-mm, and the other 75-mm gun. Where it would be logical to take one tank, with two arms, as done, for example, in the UK and partly in the USSR. In any case, such a decision would entail much less costs in the future.

The replacement of the ZIS-154 was simpler to manufacture, but less capacious 8-foot ZIS-155 (June 26, 1956-ZIL-155), the design which used the elements of the body of the ZIS-154, and assemblies of the truck ZIS-150.
No prior war had given such a diverse experience of sea action as the first world. Never before has combat experience has not been studied so carefully. And never before this experience is not done the conclusions so contradictory.

Far from the flares in Europe, the war, even the Americans in 1940 still did not think about creating your own escort destroyers. They continued to build its “big fleet”, which included a huge number of destroyers: believed that these versatile ships will be able to solve all the problems. As for specialized anti-submarine defense forces, have refused them for financial reasons: inexperienced designers managed to create a kind of “miracle of technology”, which had a displacement of just 775 tonnes, but that cost almost as much as a full 1850-ton destroyer of the “Benson”-“Glows”! It is not surprising that the squadron destroyers and favored.
When February 10, 1904 Japan officially declared war on Russia, first shots have already sounded: the Russian ships were suddenly attacked at Port Arthur and Chemulpo neutral.
