The Harkonnen-Fremen conflict is a brutal asymmetric war where House Harkonnen uses terror, espionage, and overwhelming technology to exploit Arrakis, while the Fremen utilize superior desert survival skills, guerrilla tactics, and deep knowledge of the terrain to resist. The Fremen's ultimate advantage lies in their adaptation to the harsh environment and, under Paul Atreides, their ability to threaten the entire spice supply.
