Issue 3 | New Front Lines | May 2026

A new era of warfare has arrived, and it is rewriting the rules of strategic advantage. Lessons from active conflicts around the world point to three structural shifts: (1) who can produce and replenish at scale, (2) what counts as a target in the modern era, and (3) where are wars set to be fought in future, from cyberspace to outer space. Each factor carries direct implications for logistics, legislation, and long-term policy planning.
