The document discusses the evolution of warfare through four generations and introduces the concept of Fourth Generation Asymmetrical Warfare (FGAW). FGAW is characterized by low intensity conflicts conducted by non-state actors like terrorist organizations. It is described as highly irregular, decentralized, and employing unconventional asymmetrical operations to bypass superior military powers. Modern technologies profoundly impact FGAW by facilitating networked terrorist cells and challenging distinction between military and civilian targets. Countering FGAW poses difficulties for post-modern armies due to few vulnerable targets. The al Qaeda network is presented as an example resembling the FGAW model.
