 In English, "dual-use" is an adjective used to describe technology, goods, equipment, software, or raw materials that were originally designed for peaceful or commercial purposes, but can also be adapted or used for military, non-peaceful, or defense applications.

Here is a breakdown of how it is used in context:

1. Key Contexts & Domains

• Export Control & Security: Government agencies and international bodies strictly monitor "dual-use items" to prevent sensitive commercial technologies (like advanced microchips, AI models, or chemical processing gear) from being converted into weapons.
  
  
• Technology & Innovation: Tech innovations developed for civilian markets—such as drones, satellite imaging, autonomous systems, and advanced semiconductors—often have direct battlefield applications.
  
  
• Infrastructure & Logistics: Facilities or systems designed to serve both public/civilian needs and military operational needs (e.g., dual-use ports, airports, or communications satellites).
