In the military academy of Beihai Country, there is a very interesting course, that is, chess course. Xiangqi is actually a simplified version of the military flag, which tests people's decisiveness. Moreover, by playing chess, it is easy to see the commanding tendencies of a cadet.

For example, conservative people, when playing chess, will also focus on defense. Radicals, on the other hand, are adventurous and even like to redeem their children. What you think in your heart can often be seen on the chessboard.

Moreover, the title of chess is similar to that of the army, which makes military cadets feel more immersed. Playing chess is like fighting a war, which is very much in line with the ambitions of the children in Form 2.

In fact, there is also chess in Europe, called chess. However, chess is played diagonally within 64 squares. While this rule is more flexible, it is different from the battlefield situation.

The two armies are facing each other, going straight and hedging against each other, most of them go straight and straight, how can they turn so casually? The rules of chess are not like two armies facing each other, but like two bosses and younger brothers slashing each other, which is relatively undisciplined. However, this is in line with the national conditions of medieval Europe, and the fight between two small vassal states is not so casual?

And Chinese chess, although the way of moving is not flexible enough. However, going straight and opening and closing is more like a war showdown. Moreover, in the Chu River and Han realm, the duel between the two armies, coupled with the rule that pawns are only allowed to advance and not retreat, is more like a battlefield duel, which is more suitable for the basis of war games for military cadets. In addition, there is a cannon in Chinese chess, which is more suitable for the war of this era.

Therefore, in the military academy of Beihai Kingdom, students must be able to play Chinese chess, and it is one of the most basic courses. At the same time, it is also the main recreational activity for students in their spare time.

As for the real wargame deduction, to be honest, Marin doesn't know much either. After all, he had never attended a military school, and he had not been exposed to the wargames of future military cadets.

But he knew that the war games in later generations needed to refer to the terrain, and they were often carried out directly on the sand table. Moreover, there are a lot of calculations, which need to take into account the speed of the march of different arms, as well as casualties. Even, you have to consider details such as the transportation of grain and grass.

Therefore, wargames are often confrontations between teams, rather than individuals. After all, one person counts short, and others count long. Multiple people can also do a better job of checking and filling gaps.

However, the real wargame deduction is too complicated. For military cadets who have not yet reached adulthood, it is beyond the scope of their ability. After all, the real wargame deduction is too informative, and it not only tests ability, but also tests experience and experience.

Therefore, at the elementary stage of the military academy, Ma Lin only promoted Chinese chess, not complex wargame deduction. Only at the university level, those selected high-IQ leaders are eligible to participate in the game of wargaming using a sandbox. Moreover, war games are also a daily activity of the General Staff Headquarters.

Of course, in addition to the reason why the wargame deduction is not promoted now, there is another reason that is beyond the ability of the junior officers and cadets, and that is that the wargame deduction in the Beihai Kingdom has not yet taken shape......

Although Marin is a traverser, he has never been to a military school in his last life. In my previous life, let alone wargame deduction, I didn't even use the sand table, I only saw it on TV.

Therefore, he was not familiar with the rules of wargame deduction and the calculation method. Therefore, he needs to explore with his generals. But his subordinates don't even have the concept of wargame deduction, they are not as good as him, and they can't provide much help at all. Therefore, the revision of the rules of wargame deduction can only be done by Marin himself.

He did make a few sets of plans, but his personal characteristics were too strong. Moreover, many concepts and consciousnesses that are very modern and advanced are not understood by others and cannot resonate with him. Therefore, he needs to continue to revise until he adapts to the thinking habits of most generals.

Moreover, through the revision of the rules of wargame, Marin also discovered a very important problem - insufficient mapping ability......

The so-called surveying and mapping capability refers to the ability to collect data and restore models of the mountains and rivers in specific combat areas.

At the moment, although the Beihai Kingdom has a relatively good reconnaissance unit. However, the Scouts generally have a low level of literacy, and in particular, have poor geometric drawing skills. After all, the vast majority of scouts have never been to school and don't know math.

Therefore, it would be nice for those scouts to be able to accurately depict the direction of the road and the direction of the river, and it would be difficult to perfectly reconstruct the terrain. Therefore, a lot of the information that Marin got before couldn't actually make a sand table that 100% restored the battlefield situation. In this way, there are many natural problems in such a sand table, and many places that can be used have been ignored for technical reasons.

But you can't blame the scouts, who are illiterate, don't know geometry, don't know how to draw, and it would be nice to find the right path. As for the appearance of the mountains and rivers, I can only sketch them very roughly. For example, the mountains are very high and the water is deep......

Therefore, for the sake of convenience in deduction, Marin has begun to set up a surveying and mapping course in the Beihai Military Academy. Not only did they begin to train surveyors, but they also required artillery officers to be proficient in surveying and mapping.

Marin remembered that in history, the famous German general Moltke was an officer engaged in surveying and mapping, and attached great importance to the application of technology. He made surveying and mapping an important tool in the army, and also introduced statistics and geography, and attached great importance to railways and telegraphs. Therefore, in the Franco-Prussian War, the Prussian army mobilized and assembled and put into the battlefield faster, forming a local superiority over the French army, and finally won the war.

Moreover, before the Anti-Japanese War, the devils also sent a large number of surveyors, disguised as businessmen or tourists, to travel all over China, surveying and mapping the terrain and mountains in detail, and even surveying and mapping the layout of various cities for reference in the future.

Later, when the devils invaded China, the maps taken out by the officers were much more accurate than the official maps of China. If it weren't for the fact that Huaxia was too big, the devil's manpower was limited, and the oil supply was difficult later, the devil knows what serious consequences would be.

Although, the devil is the villain. However, for Marin, some of the practices of the devil back then are also of reference to him. For example, if he wanted to annex the northern half of Germany, he had to make all kinds of preparations. For example, the direction of mountains and rivers is clear. In this way, it can bring a lot of convenience to the marching battle. Where you need to fight, all you need is a military map.

For this reason, Marin decided to learn from the practices of the devils back then, and prepared to cultivate a group of masters who are proficient in map surveying and mapping. Then, they were sent to disguise themselves as caravans and travel all over Germany, depicting the mountains, rivers, and roads in preparation for the future annexation of these places.

Because they were all Germans, Marin didn't even need these surveyors to learn foreign languages, they only needed to learn surveying and mapping techniques. After all, everyone speaks German, so you don't have to learn another language. As for the dialect problem, it's not a big problem, as long as you can barely communicate. After all, even in later generations, it is not surprising to encounter merchants with foreign accents.

You know, in the past, the devils were surveying and mapping, but those who let those people learn Chinese are much more demanding than purely training surveyors. After all, in addition to understanding surveying and mapping, they also need to master a foreign language, which is very demanding.

The surveyors of the Beihai Kingdom only need to know how to draw distances, heights, maps and contour lines.

As long as the surveying and mapping work is done well, when troops are sent to unify northern Germany in the future, they will be able to achieve twice the result with half the effort. Wherever you go, you can come up with a detailed military map to facilitate decision-making.

Moreover, if the surveying and mapping data is detailed, it can even restore the local topographic sand table for officers to conduct war games and improve the chances of winning the battle......
