A joke about being an artillery.

An artillery went to the battlefield, and boom, there was a border conflict between country A and country B. After a battle, a soldier from country A was captured and put in a prison in country B, but a few months later, the soldier got a strange disease. First, the left leg was inflamed, and finally I lost consciousness and had to amputate. The soldier asked him if he could send this leg back to his own country. Moved by his spirit, country B agreed. But soon his right arm was cut off because of the same disease. He asked to be sent back to country A, and B agreed. Later, this happened to his right leg. When he asked for it again, country B refused. He was puzzled and asked why. The official of country B said with a serious face: "We suspect that you are planning to escape in stages and batches."

There is no war, so I'm fine first.
