Indian Threat Scenario, National security threats and future military capability requirements
There are two approaches to connect Warfighting and emerging technologies. One is to consider the present and future threat environment and then through system analysis we can identify technologies required to mitigate those threats. Secondly, we can identify the emerging technologies that can offer new military capability. Coming to …
