Yes, because the shelf life of military food is usually very long, 3-5 years. Once the military food leaves the factory, it needs to be stored in the war preparedness warehouses for a period of time, usually one year. If it is not used after one year, it will be disposed of if it can keep up with the production in peacetime, and then a new batch of goods will be imported to ensure the freshness of war preparedness materials at all times. This part of the food stored for more than a year has not expired, and a large part of it has entered the civilian market. Some people can also get a batch of food at the right back door of the army, because food is only food after all, not a managed product, and there is nothing to keep secret. Military compressed biscuits are generally true, because no one makes fake military compressed biscuits, and the production cost of compressed biscuits is very high, because it needs a production machine for compression. Outside the armory, there are few civil compressed biscuits available on the market, and the sales of compressed biscuits are also very small. Most people don't like them very much. They are used for wild survival and war. Because of their convenience and long storage time, they can be used as emergency reserve food.
