Principal Chen turned off the stopwatch, unscrewed the military kettle and handed it to Ye Jian, "My intensive training is different from general intensive training. You also need to memorize the locations of each province, country, and the longitude and latitude of the north latitude. The models, differences, and range of guns and ammunition will be tested."

Strengthening training not only requires physical fitness, but also memory strengthening!

Ye Jian got up from the bushes after two minutes of rest, and his black eyes were as bright as a black stone. "Everything is followed by your arrangement. I have already rested and can move on to the next step of training."

"Tell me about the same classification of maps. Since Major Xia still hopes that you can command, you will understand the map." Principal Chen opened a light aluminum folding table for marching, which is 50 centimeters long and 30 centimeters wide, and spreads out a military map. He said with a tough voice and a serious voice: "The map can be divided into ordinary maps and special maps, and can be divided into teaching maps, political district maps, military maps, flight maps, etc. according to their purpose."

"What I want to talk about next is military maps, including special maps such as nautical charts, aviation grounds, etc. The military's combat operations cannot be separated from maps, and the relevant information on terrain and land objects are reflected through maps."

"The map is the eyes of the army and the silent guide. You must understand it no matter when you are and be able to draw it immediately! You need to have a certain knowledge of using graphs, have six basic elements, and complete the drawing of military topographic maps."

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

"The plane rectangular coordinates on the military map are different from Cartesian coordinate system in mathematics. Its meridian line is the coordinate vertical axis X, and the equator is the coordinate horizontal axis Y. Look here..." The pencil gently scratched a military map to indicate Ye Jian to see clearly, "This is the vertical axis X, and this is the coordinate horizontal axis Y."

Ye Jian has always absorbed these profound and difficult professional knowledge quickly. Principal Chen will know it once and give an example.

"...Magnetic azimuth angles must be widely used when marching in the army, artillery, artillery, aviation, and navigation. When drawing military maps, this must be understood and clearly marked, such as this..."

Taking out a piece of white paper, Principal Chen quickly drew it with a pencil. In a short while, a simple marching and military map appeared on the white paper.

"After learning to draw a military map, you must also know how to study the map on the map, and conduct comprehensive analysis, research and judgment based on the characteristics of the army, the tasks received and the enemy situation, and the weather seasons. Only after you understand everything and master it can you decide on combat operations."

These are the knowledge that a commander needs to understand and the abilities that a special forces soldier must possess.

Ye Jian listened very seriously and was even fascinated!

From this I soon learned the importance of military map mapping, researching and arranging operations on the map.

I also know how much impact the terrain analysis has on military maneuvers. You must know how many railways it takes to pass through the entire marching maneuvers. If there is still armored maneuvers, how long and wide the bridge it passes, and the specific load-bearing weight... These commanders must master them one by one!

Only by knowing these, understanding these, and mastering these can we analyze and judge the possibility of opportunities along the road and off-road, as well as logistical delivery, etc., can we be sure to win the battle!
