Join us as we explore how the intricate interplay between geology and military strategy has shaped history. We unravel the secrets behind the terrain's influence on battles, from its impact on troop movements to the potential for fortifications and natural defenses. Additionally, we investigate an intriguing question: What type of rock is the deadliest? We are astonished by the unexpected ways in which geology has played a pivotal role in shaping the destiny of nations in times of war.
