No matter in which era, the training of the army is very important and the top priority of the country. Only by improving the military strength of the country can the country have an equal position in the world. In the army, every soldier is particularly important and needs to be equipped with a lot of equipment to survive on the battlefield. Among these equipments, weapons are very important, after all, they are used for fighting, but the most basic equipment is the military kettle, which determines the survival of a soldier and can provide the basic conditions for survival. Not only that, the military kettle has other functions. It can be said that although the military kettle is simple, it contains high technology, which many soldiers have not found.

　　In the process of development, the military kettle was just a particularly simple vessel for holding water at first, but with the development of the times, the military kettle has become more exquisite and has more and more functions. First of all, because the battlefield environment may be ever-changing, the water quality of its water source is not very good. And soldiers need to survive in such a cruel environment, so they must be able to replenish water in their bodies with enough water. The military kettle has designed a function, that is, the filtering function, which can filter the fresh water quality in different environments and then supply it to soldiers to avoid adverse reactions such as stomachache.

　　In addition, the appearance of the military kettle is also more exquisite, and the materials used are also very advanced, which can ensure the sealing of the kettle and avoid its water evaporation. We see on TV that military kettles are usually packed in colorful bags, and with the development of the times, their design is more ingenious, not only retaining the bag protection, but also designing the appearance of their kettles, which makes them more durable and wear-resistant, and can not be damaged in various environments.

　　In addition to the above functions, the military kettle is also designed to keep the water temperature. It is said that its appearance adopts a double-layer vacuum structure, which can effectively keep the water temperature in a cold environment and provide water for soldiers in a cold environment. In short, with the development of the times, the military kettle is also designed to be more humanized.
