Which term refers to intelligence concerning foreign technological developments applicable for military purposes?

The term that refers to intelligence concerning foreign technological developments applicable for military purposes is Technical Electronic Intelligence (TECHELINT). This area focuses specifically on the technical aspects of foreign military capabilities, including their systems, technologies, and operational methods. It encompasses the analysis and understanding of weapon systems, platforms, and operational concepts that could pose a threat or offer opportunities for military advantage.

TECHELINT is integral to developing strategies and countermeasures as it informs decision-making and capability planning within military contexts. By assessing foreign technological advancements, military organizations can adapt and enhance their own technologies and tactics, ensuring preparedness in a rapidly evolving threat landscape.

The other options describe different facets of electronic warfare and intelligence. Operational Electronic Intelligence (OPELINT) is more focused on the operational aspects and how systems are utilized in the field, while Electronic Intelligence (ELINT) relates specifically to the interception and analysis of non-communication signals emitted by foreign radar and weapons systems. Communication Intelligence (COMINT) deals with the interception and analysis of communications. While all these terms relate to intelligence and electronic warfare, they do not specifically target the evaluation of foreign technological developments in the same way as TECHELINT does.
