One of the most formidable military machines is the tank. With an armored exterior that keeps its small crew safe inside, a tank can easily navigate uneven ground and fire its cannon in any direction. Prompted by the changing nature of war, the design of tanks has developed over time to meet new needs. This book provides readers with an overview of that evolution and a glimpse into the future of military tanks. Full-color photographs and a labeled diagram illustrate the engineering behind these powerful vehicles.
