The Flak 38 is a German towed 20mm automatic anti-aircraft gun from the Second World War. The first prototypes of the plot were created in 1938, and serial production began shortly after. The maximum vertical range was 3,700 m, and the initial velocity of the projectile was 900 m / s. Theoretical rate of fire was up to 420 rounds per minute.
The Flak 38 was developed by the Mauser company as a far-reaching modification of the Flak 30 cannon. First of all, the theoretical rate of fire was increased in the new cannon and the general mechanical structure was improved. This improved the parameters of the weapon, however, as shown by the combat operations of 1940-1941, the Flak 38 still had too little firepower, which it was decided to increase by creating a quadruple cannon - this is how the 2 cm Flakvierling 38 was born. Both versions of the cannon were massively used by the Wehrmacht in progress World War II in 1940-1945. They also served as an armament for several vehicles, including: Flakpanzer 38 (t), Mobelwagen and Wirbelwind.
Einheitsdiesel (full name: Einheits-Lastkraftwagen) is a German universal truck from World War II. The first copies of this vehicle appeared in the mid-1930s, and serial production continued in 1937-1940. The vehicle was powered by a single 80 HP MAN engine. It is worth noting that many German companies were responsible for the production of this car, for example: Bussing-NAG, Daimler-Benz, FAUN, Vomag and Magirus.
The first work on the Einheitsdiesel truck took place in 1934, when the German armed forces reported a need for a new three-axle truck with a carrying capacity of 2.5 tons. Finally, after a series of tests, a successful truck was created with very good off-road ability, little breakdown, and easy to repair and maintain. The vehicle was also relatively cheap to produce. On the other hand, the truck required careful and careful maintenance and had a suspension that was very prone to breakdowns and damage when transporting loads greater than the permissible load capacity. Especially the last drawback meant that by the end of 1940 the mass production of this car was stopped. On the basis of the basic version, several specialized versions were created, such as a communication car (Kfz.61) or a car with a crane located in the load compartment.
