Sun Tzu's Art of War, Chapter 10, emphasizes the crucial role of terrain in military strategy. Six types of terrain are defined—accessible, entangling, supporting, constricted, precipitous, and distant—each demanding a unique tactical approach. The text also details six common military failures stemming from poor leadership, not unfavorable conditions. Ultimately, success hinges on a general's understanding of terrain, enemy capabilities, and their own troops' strengths, coupled with prioritizing the welfare of the people.
