Actually, you don't have to worry. It is not illegal to sell rations, because these rations are not for the exclusive use of the army and can also be sold in the society. In order to ensure that the troops have enough rations reserves in an emergency, manufacturers who sign contracts with the troops will overproduce, some of which will be digested by the troops and some will be stored as reserve materials. Once the situation occurs, the pressure of emergency production will be much less.

When a new batch of rations comes off the assembly line, the last batch of field rations as additional reserve materials will be sold by manufacturers to dealers and enter the social market. Once this step is reached, these rations will be very daily commodities, not military products. In addition, the shelf life of rations is not short, so it is no problem to sell these materials directly to the people as reserves. Manufacturers can overproduce and flow directly to the social market to earn profits without wasting time.

Here, I want to remind you that there are two kinds of field rations purchased by our army at present: 09 and 13. In addition to the standard style, 09 has 12 different recipes, while 13 has four. Styles and menus are easy to find online. If the shops you find have all kinds of strange smells and styles, they are not produced by regular arms manufacturers, but imitations produced by some small factories in society.

As for buying foreign rations, there is no problem in theory, because military rations in many countries are not sold, so you can buy them directly in the supermarket. For example, Israel's military rations are 100% dual-purpose, and canned kimchi, beef jerky and energy bars are all edible foods at ordinary times.
