In fact, at that time, due to the different degrees of economic development and attacks, there was a big gap in food among countries, among which the food in the United States was the best, because the United States was the most developed country in the world at that time, so it had enough economic ability to support its military food development. Of course, in many countries, such as China and Southeast Asia, there are many phenomena of eating grass roots and chewing bark, mainly because China was a very poor country at that time.

At that time, due to the perennial war, China's economic development was not so excellent, and more importantly, it did not get a very favorable guarantee in logistics support, which also caused many soldiers to suffer from malnutrition. However, due to the economic development, the fruit condition of China's army has gradually caught up with the forefront of the world, which also makes the fighting capacity of China's army slowly catch up, because food is the most important thing for the people.

At that time, however, its military meals in the United States were too superior, because the United States was the most developed country in the world at that time, and it needed to maintain its economic and military status by maintaining a strong army. Therefore, Americans are also very unambiguous in military meals, which can be said to be the country with the highest food standard in the world at that time, and they also actively improved after the war, which made many countries far behind.

Of course, a country's military food standards are formulated according to the country's economic development. However, in the Second World War, many countries were in a very poor and backward phenomenon, so there was no very standard military food regulations. Therefore, it also led to a variety of military meals in many countries at that time, and they often ate whatever they had. However, after the war, with the development of economy, the military meals were gradually standardized and industrialized.
