Then Andrei said: "Now the German offensive is still strong, we must hold on now, if the brother troops are finished, we will inevitably be attacked by the German army from all directions, so the opinion of the political commissar is very correct, we must next form a combat group composed of assaulters, snipers, machine gunners, in the urban area for the small units of the German army to strike and harass to reduce the pressure on the brother troops!" ”

Hearing that his opinion was adopted, Brezhnev was very happy, you must know that he is not the old bureaucrat of later generations, nor is he the general secretary of the amazing power, he also has the ambition to continue to climb up, so when he received the order to come to Stalingrad as a political commissar, he chose to come to the order, you must know that although the director of the political department is the leader of the group army, but in the case of a political commissar, his own director is not important, and compared with the chief of staff, it is nothing. And the political commissar of the main division who sticks to an important position, although the level is about the same, but it is a rare opportunity for himself, you must know that military merit in the army is the best seniority medal, and you can also have the connections of this army, before coming he also knew the situation of the division commander, Andrei Yalun Yakov is a rising star of the Ministry of Internal Affairs has received the attention of the Supreme Commander himself, the political future is still very good, and Beria is also very cultivated, this is an important opportunity, therefore, after coming to the division headquarters, Brezhnev did not have a second-in-command frame at all, but was very polite to everyone in the division, uniting all those who could be united, of course he was the leader, but he was not separated from the masses, so that he could have good connections, and through this period of contact, Brezhnev also knew that Andrei was indeed very capable, as long as this battle could be won, he would definitely be further promoted, and as the political commissar of the Siberian Volunteer Division, the next will naturally be indispensable. And he found that although Andrei emphasized military democracy, he was a military commander after all, so he had an attitude of harmony and cooperation on all issues, but as a political commissar, if he did not have a role at all, he was too weak, you must know that in the army, as an important leader at the first level, he can be mediocre but not incompetent, otherwise how to climb in the future, incompetent people in wartime are not eye-catching!

So for the war situation Brezhnev chose to speak, and now that the suggestion has been adopted, he is also very happy, and Brezhnev also said before his death in the future: "My happiest time was during the Great Patriotic War and when I was the secretary of the state party committee, because at that time I didn't need to have so much intrigue with my own people but only thought about completing the task better!" ”

However, at this time, Andrei didn't know that Brezhnev had so many twists and turns, and now he was just thinking about how to fight better. Pen ~ fun ~ Pavilion www.biquge.info After all, the bloody battle in Stalingrad is still going on!

In this way, the staff officers of the division headquarters arranged the support of the detachment, and now everyone was waiting at the division headquarters for nightfall, because there would be an important raid and harassment operation at night.

First of all, the group outside the division headquarters took out portable surveying equipment to further the accurate range, in the First World War, there was a simple geodesy, at that time according to the map with simple equipment and operating methods for artillery positions, observation posts for positioning and directional surveying. With the development of artillery performance and shooting technology, artillery shooting command has put forward higher requirements for geodesic accuracy. After the advent of sophisticated optical measuring equipment, precision geodesy appeared, which could accurately determine the relative position of the target to the artillery. In fact, as early as 1888, the Englishman Stroud invented the monocular convergence rangefinder. In 1892, France Groussilier designed a binocular stereo rangefinder, but the error was large, and by the time of the Second World War, there was a stereo rangefinder that was not out of balance, which was less affected by the environment and improved the accuracy of ranging. In the 60s of the 20th century, artillery laser rangefinders appeared, with a large volume and weight. In 1977, the United States was the first to successfully develop the world's first artillery portable hand-held laser rangefinder

Although the equipment carried by the signal flag is not as good as that of later generations, it is still ahead of the times, you must know that the Soviet Union itself is a country that attaches importance to artillery, so it has always been at the forefront of the world in artillery tools. In the 50s of the 20th century, artillery began to use gyroscopic orientation technology for measurement, and with the traditional optical rangefinder, in fact, various prisms or mirrors in the optical rangefinder will overlap the images in the two viewfinder windows, and what people observe through the last eyepiece is two overlapping images. By adjusting the prism or mirror in the rangefinder, the user can overlap two images coming in through the viewfinder and then read the exact shooting distance of the corresponding object from the dial on the rangefinder. In fact, the basic principle of the optical rangefinder is the principle of triangular measurement, in other words, the distance from the two viewfinder windows to the target is not exactly the same, and these two distances plus the distance between the two viewfinder windows form a triangle, and the principle of measurement is based on this triangle. From the simplest optical rangefinder, we can see that the optical axis of the eyepiece is always the same axis as one of the two viewfinders. Inside the rangefinder, the image transmission path between the two viewfinder windows is completely perpendicular to the optical axis of the eyepiece. From this, we can see that, to be exact, the optical rangefinder uses the right-angle triangulation method. When the object is in a different position, the angle between the hypotenuse and the right-angled edge of the right-angled triangle is completely different, and only when we adjust the position of the prism or reflector, can we re-establish the right-angled triangle; The amount of angular change we derive from the position of the prism or mirror allows us to calculate the actual distance from the photographed object. Using such simple geometric laws, we solved the ranging problem encountered in the actual shooting. When it comes to the measurement accuracy of the optical rangefinder, as long as you understand the Pythagorean theorem, you will know that the distance between the two viewfinder windows directly determines the accuracy of the measurement, and the longer the distance between the two viewfinders, the higher the accuracy of the rangefinder. But traditional equipment is too big and heavy, and now it is easier to target and determine with new technology.

At the same time, the raid on the artillery camp began, and the Vympel unit had prepared a secret weapon for the Germans this time.
