In order to adapt the changes of special operations, the study of special operations command information systems is carried out. Based on the summarization and analysis that special operations command information systems shall have 5 core capabilities: various communication networking methods, multi-level cubic command, multi-force flat coordination, multi-segment precise information mastering and multi-mode rapid conversion, the exploration describes in brief the key technology of special operations self-organized network, troops capability estimation and multi-source target correlation process. The study may provide some reference for further study of special operations command information systems.
