Aiming at the problem of intelligent unmanned combat, the development characteristics and laws of artificial intelligence (AI) technology, intelligent weapons and combat forms are studied. This paper expounds the policies and measures of various countries in the field of developing artificial intelligence technology and intelligent combat, focuses on comparing the characteristics and application scope of deep learning technology and deep reinforcement learning technology, analyses the characteristics and advantages of current intelligent equipment and intelligent unmanned combat, and analyses the possible development trend of future unmanned intelligent combat platform. The comparative analysis results show that the analysis and research have accelerated the transformation of the current war form to the direction of intelligence, unmanned and informationization, which has led to extensive and profound changes in operational concepts, operational forms and weapons and equipment, having development opportunities for the new situition of future warfare.
