On the battlefield, human-computer collaboration has been replaced by artificial intelligence, at least for the moment it is difficult to happen in a short time. The problems that artificial intelligence can solve are limited. Replacement will first occur in some areas, but human-machine collaboration is still inseparable. The main means of implementing artificial intelligence is machine learning, and deep learning is a way to achieve machine learning. Although deep learning has achieved very good results in many fields at present, but it involves tasks that require creativity on the battlefield, can not give clear definitions and boundaries, and lack of digital knowledge experience. So for a period of time in the future, machines will play a more auxiliary role in the field of combat, and the final decision-making is still inseparable from humans.
