[Machine Translation] Amid talk of major reductions in tank units, the Ground Self-Defense Force is currently operating four types of tanks in the midst of an offshoot of equipment renewal. These four types are the Type 74 tank, which has been in service for over 40 years and is now on the verge of retirement; the heavy and powerful Type 90 tank; the refurbished Type 74 tank (G), of which there are only four; and the Type 10 tank, which has been deployed for three full years as the world's most advanced tank. This book introduces various types of exercises and operations, as well as special specifications, variations, and detailed photographs. In addition to perspectives from all four sides, the book also makes full use of oblique perspectives, such as heavy machine gun fire methods and how to set up a disguise net. Interviews with senior officers of the armored division are also included.
