Explaining what William McNeill called The Rise of the West has become the central problem in the study of global history. In Guns, Germs, and Steel Jared Diamond presents the biologist's answer: geography, demography, and ecological happenstance. Diamond evenhandedly reviews human history on every continent since the Ice Age at a rate that emphasizes only the broadest movements of peoples and ideas. Yet his survey is binocular: one eye has the rather distant vision of the evolutionary biologist, while the other eye–and his heart–belongs to the people of New Guinea, where he has done field work for more than 30 years.

From the beginning in 1935 this attractive book describes the different elements that went into the Panzer-Divisions. It describes how the Germans carefully built up their assault forces utilizing all available reserves and resources into making an effective fighting machine. It depicts how these awesome formations grew to be used four years later in war, and provides much historical information and facts about the vehicles and its components that fought in all the campaigns of the war from the early victorious Blitzkrieg in Poland and France to the last ditch defense in Germany in 1945. Each chapter features unseen photographs of light tanks, main battle tanks, assault guns, anti-tank destroyers, artillery, reconnaissance units, support vehicles, pioneers with their bridge building platforms and the motorized infantry or Panzergrenadiers.
