The research on individual soldier field rations has been in our army for decades, which can be summarized as "three generations". Representative products include scout food, special individual food and ordinary individual food. The first generation is war food. It consists of three staple foods: compressed dry food, dehydrated noodles and dehydrated rice, and three non-staple foods: canned lunch meat, canned stir-fried meat and canned diced meat with sauce. During this period, military rations have formed a structure of matching main and non-staple foods. The second generation of Lu Qin series field food, such as dehydrated rice. In China, soft-packed canned food and dehydrated rice were first developed by our army in China. These foods are actually fast food, including rice, vegetables and soup, which is in line with the eating habits of officers and men.

In the third generation development period, a new type of "instant noodles" came out, which not only tastes better than civil instant noodles, but also can be soaked in boiling water or cold water, and its convenience made the world applaud. This noodle has won two national invention patents. At the same time, our army's fast food rice has also been successfully developed and will be equipped with troops one after another. However, there are some problems in the use of the above products, and some staple foods (mainly canned rice and noodles in soft packages) cannot be eaten normally because of starch retrogradation. Therefore, as an important problem to improve our army's battlefield food support ability, the hot food of individual rations is one of the problems to be solved urgently in our army's logistics support.

Although the first consideration of military rations is to meet the human body's intake of various energy in combat situations, especially the heat must be guaranteed, and the demand for taste is naturally behind, but for soldiers, if it is a military rations with the same taste and wax all day, it will definitely affect appetite and eating. If they eat less, they will reduce their calorie intake and indirectly affect their combat effectiveness. So now countries pay more and more attention to the taste of military food.

It can be said that compressed biscuits are the first kind of dry food equipped by our army after fried noodles, which made great contributions in the era of lack of food and materials. The related production enterprises produced in large quantities, and the inventory was so amazing that many troops were still eating compressed biscuits produced many years ago during the exercises in previous years.
