Engineers in military engineering

Army marching needs to build roads and bridges, army fighting needs to dig fortifications, and army camping needs to camp. These tasks belong to the technical aspects of civil engineering and are completed by the army's professional arms engineers. Military engineering has existed since ancient times, and the Great Wall in ancient China is the largest defense project in the world. In addition, there are castles, water villages, trenches and fences. With the development of the times, weapons have improved, combat methods have changed, and the content of military engineering has also expanded. There are positional projects, such as permanent fortifications for border defense and coastal defense; Urban underground air defense works; Command and communication projects such as command post, radar station and satellite communication ground station; Military traffic engineering, such as national defense highway, military road network, bridges, ferries, pontoons, oil pipelines, water pipelines, etc. ; In addition, there are military ports, airports, weapons proving grounds, training bases, logistics warehouses, barracks and shooting range projects. All the above are constructive work, and military engineering also includes two special tasks; One is blasting and the other is camouflage. Blasting may be needed in military engineering construction. Blasting can be used to open channels in obstacles and blow up enemy fortifications, bridges and dams. Burying mines and clearing them are the tasks of engineers. Camouflage is a protective measure. In peacetime and wartime, engineering camouflage measures are taken for various military facilities and military operations to confuse the enemy and make it impossible for the enemy's reconnaissance to find out; Sometimes it is necessary to make and arrange some fake targets, or even build fake ferries, fake airports and fake buildings, so that the enemy can't tell the truth from the truth and mislead the enemy to attack the fake targets, thus protecting the real targets and the real actions of the troops. With the continuous development and progress of science and technology, many new technologies and materials have been applied to the field of military engineering. There are more and more tasks for engineering troops. For example, in the case of natural disasters, such as floods, earthquakes and storms, engineers are often sent to rescue and provide disaster relief.
