Principal Chen turned off the stopwatch, unscrewed the military kettle and handed it to Ye Jian, "My intensive training is different from ordinary intensive training, you also need to memorize the locations of each province, the place of each country, and the latitude and longitude and latitude of the north. I will also test you on the models, differences, and ranges of guns and ammunition. ”

Intensive training is not only about physical fitness, but also about memory enhancement!

Ye Jian got up from the bushes after resting for two minutes, his dark eyes were as bright as black stones, "Everything is up to your arrangement, I have rested and can enter the next step of training." ”

"Let's talk about the same classification as the map, since Major Xia still wants you to command, you have to understand the map." Principal Chen opened a light aluminum folding table with a length of 50 centimeters and a width of no more than 30 centimeters for the marching army, spread out a military map, and said in a tough and serious voice: "The map can be divided into ordinary maps and thematic maps, and can be divided into teaching maps, political maps, military maps, flight maps, and so on according to their uses. ”

"The next thing I'm going to talk about is military maps, including nautical charts, aeronautical maps, and other special maps. The army's combat operations are inseparable from maps, which reflect relevant information about the terrain and features. ”

"The map is the eyes of the army, the silent guide, you must understand it at all times, and be able to draw it immediately! You need to have a certain knowledge of map reading and mapping, and have the basic elements of six aspects to complete the drawing of military topographic maps. ”

Principal Chen is erudite and very meticulous in teaching, and his low and deep voice allows Ye Jian to listen attentively and quickly digest these professional knowledge.

"The plane Cartesian coordinates on the military map are different from the Cartesian coordinate system in mathematics, its meridian is the vertical axis of coordinates X, and the equator is the horizontal axis of coordinates Y, you look here......" The pencil lightly stroked on a military map, signaling Ye Jian to see clearly, "Here is the vertical axis X, and here are the coordinates on the horizontal axis Y." ”

Ye Jian has always absorbed these esoteric and difficult professional knowledge quickly, and President Chen only needs to talk about it once and give an example, and he will have a number in his heart.

“…… Magnetic azimuth is widely used in military marching, artillery archery, aviation, and navigation, and this is absolutely necessary to be understood and clearly marked when drawing military maps, such as ...... like this."

Taking out a blank piece of paper, Principal Chen took a pencil and drew it quickly, and in a moment a simple military map of the march appeared on the white paper.

"Once you have learned to draw a military map, you must also know how to study the map on the map, and conduct comprehensive analysis, research, and judgment according to the characteristics of the army's arms, the tasks and enemy conditions that you have received, and in combination with the weather and seasons.

These are the knowledge that commanders need to understand, and they are also the abilities that a special soldier must have.

Ye Jian listened extremely seriously, and was even fascinated!

He quickly learned the importance of military mapping, map research and analysis, and battle arrangement.

You also know how much impact terrain analysis has on the mobility of the army, how many railways and highways the entire marching maneuver has to pass, and if there is still an armored maneuver, how long and wide the bridges are crossed, and how specific the load-bearing capacity is...... These commanders have to be mastered one by one!

As long as we know this, understand this, and master these skills, we can analyze and judge the possibility of various arms along the road and off-road opportunities, as well as logistics forward, and so on, in order to be sure of winning the battle!
