Since the wheel has been invented, the “war” and “wheels” have been together in humans. The carriage wheel not only greatly expands human mobile, but also has changed political, economic, industrial, technology and even war, providing opportunities for changing road transport systems. Especially in the war, compared with the use of livestock or walking transport, carriage wheels were used regardless of the orientation and Western countries. It can be said that in the era of carriage, the civilization of East and Western is almost.
In fact, until now, the main tools of land transport are still “railways” and “car”. But at that time, it was still the era of carriages, although there were already cars, but technology did not be so reliable now, and it is a bit difficult to maintain it. In addition, the productivity is not as good as it is now, so it is difficult to produce 1,000 cars per month even if the factory has endless operation. Therefore, the military who was very conservative was reluctant to use the car in the war.
However, as the first World War became an unprecedented consumer war in human history, it has changed in the case of using the car.
In particular, the entire country has become the French battlefield, and you have to mobilize various means to make up for the lack of transportation. In a battle in the Marne, 600 vehicles were used to transport 6,000 soldiers, although this is only a few, but France has won the first in this motor transport. Field battle. Therefore, during this time, the French army began a serious way to seriously transport the car as an important tool for war transportation. At the beginning of the war, the number of cars was only 6,000, and at the end of the war, the number of cars reached 100,000.
At this time, the car not only starts to be used as a cargo transport, but also Used as a mechanized infantry armored vehicle, carry a small number of troops and engaged in motor operation. The Rolls Royce armored car in England is a good example. It is equipped with a Victor gun with excellent firepower, while moving faster than the early tank. In addition, car manufacturer Renault(Renault) developed Renault FT tanks, the tank was regarded as the origin of modern tanks in this war, making great contributions to the leaders Allied in the First World War.
The transportation capacity of cars in the first World War left the world A deep impression, many countries in the world began to introduce cars into their troops. In 20 years, the second World War is coming, and the share of automobile transport has increased. 
In particular, when entering the war system, a large number of cars are poured and placed on the front. On the other hand, in the German army situation, the production capacity of the car is absolutely not bad compared to the United States.
Today, in addition to certain special cases, today’s armed forces, especially ground troops have all achieved mechanization. Cars have been completely associated with military.
