  The development of U.S. Army and NATO data link systems is introduced first,
and then the development trend of future intelligent data link is summarized
into integration, generalization, multifunctionality and high security. A
unit-level combat system architecture based on the global combat cloud, which
is capable of realizing the flexible scheduling of global combat resources and
maximizing the overall combat effectiveness, is proposed. Intelligent data link
is an important part of this solution, providing strong information support for
future urban unit-level warfare.
