Based on the experience of World War I, the German army paid a lot of attention to the development of both light and heavy infantry machine weapons in the interwar period. The result of these efforts was the introduction into service in 1934 of the very successful MG34 machine gun, which replaced the less handy and much heavier MG08 or leMG 08/15 rifles. During World War II, another, equally successful, but cheaper to produce design was introduced - the MG42. Both of these rifles were de facto the basic machine weapons of the German infantry and armored grenadiers during World War II. Their very high rate of fire and high ballistic parameters meant that they were perceived as the basic support weapon at the level of a platoon or company, and often even a team. Interestingly, thanks to the relatively low weight, they could be successfully used both in offensive and in defense. Very often, in the course of combat operations, the soldier responsible for servicing the MG34 or MG42 was assigned from 2 to 3 ammunition to ensure that the rest of the team was firing machine guns uninterruptedly.
Battle for Kharkiv was played from February 21 to March 18, 1943. It is assumed that about 70,000 soldiers took part in the battle on the German side, while on the Soviet side - about 340,000. soldiers. On the German side was commanded by Field Marshal Erich von Manstein, while on the Soviet side - Marshal Filip Golikow. The genesis of the Battle of Kharkiv in 1943 dates back to the German defeat at Stalingrad in February 1943 and the Red Army's move to the west offensive in the area of today's south-west Russia, which was aimed at the German Army Group "South". At the beginning of February 1943, Soviet troops liberated, among others, Kharkiv, Kursk and Belgorod. At the same time, however, despite the successes, the Soviet troops were stretched significantly, their logistics was defective and, above all, they suffered relatively high losses in the course of their offensive operations. In this situation, despite the significant numerical superiority of the enemy, the German troops (especially armored forces - including the 2nd SS Panzer Corps) launched the offensive and in the period from February 21 to 28, 1943, they encircled and destroyed the Red Army troops fighting south of Kharkiv. On March 4, the II Corps entered the city, retaking it from the Soviet hands until March 15, and three days later Belgorod was recaptured. The Battle of Kharkiv stabilized the eastern front until the Battle of the Kursk in July 1943. In the course of the fighting, the Soviets lost about 80,000 people, while the German side - about 11,000 people.
