The term "Pin-Up Girls" derives from a trend that was clearly perceived in the 1940s and 1950s in the United States. It concerns posters hung by men from various social classes (most often by blue collar workers or soldiers, but not only!) With specifically dressed and make-up women with a clear erotic tinge. Let us add that although these posters were erotic, they were not treated as pornography, which was forbidden in the US at that time. These "Poster Women", that is the Pin-Up Girls, were always smiling, they wore either flared, loose polka dot or striped dresses, or very skimpy underwear, or bathing suits. They were often depicted wearing high waisted shorts. Of course, the Pin-Up Girls outfits were presented in such a way as to reveal as much of the models' bodies as possible. Let us add that also many official photos of Marilyn Monroe are kept in this style. The makeup used was also very clear with red lipstick underlined on the lips and strong black lines above the upper eyelids. It is worth adding that from the beginning of the 21st century there has been a noticeable renewed fashion for styling and makeup in the spirit of Pin-Up Girls.
Armored and mechanized troops of the Red Army began to be formed on a larger scale in the late 1920s and 1930s. Especially in the 1930s they developed dynamically. This was reflected both in the organizational structure and in the equipment. On the first of these planes, the formation of mechanized corps began in 1932, the structure of which evolved until the outbreak of World War II. As for the equipment - new types of tanks were introduced, such as the BT-5, BT-7, T-26 and the T-28 multi-turret tank. Very successful tanks also introduced into the line shortly before the start of the war with the Third Reich - of course, we are talking about the KW-1 and T-34. However, despite the fact that at the time of the German aggression, the Soviet armored forces had a quantitative advantage over the aggressor, they suffered huge losses in men and equipment in the first period of the war. They can be explained by the shortcomings of a well-trained officer cadre (the aftermath of the Stalinist purges of the 1930s), worse individual training of Soviet tankers compared to their German opponents, or inferior tactics used by the crews of Soviet tanks. Also, the doctrine of their use was not as consistent and well-grounded in training as in the German army. We can also add to this the rather poor ergonomics of Soviet vehicles or the shortage of short and long-range radio stations in armored forces. With time, however, these errors began to be more or less successfully corrected. For example - from the spring of 1942, armored armies began to be formed, which were to perform primarily offensive tasks and which constituted a slightly more ergonomic structure than the previous mechanized corps. However, it seems reasonable to say that until the end of the war, the Red Army emphasized the quantitative advantage rather than the qualitative advantage over the enemy, although it introduced such successful tanks as the T-34/85 or IS-2 into service during the warfare. This is clearly visible, for example, during the Battle of Kursk in July 1943.
