Query: M60, a commander's remembrances.

Having commanded am M60A1 at Fort Knox during the mid 60s it was fun to renew an old friendship. The smell, vibrations, the sound of the tracks and the fury of the main gun firing brought back many good memories. Once a track driver, always a track driver as the saying goes. The book covers the history and development of this fine machine including its use in the mid-east wars of the last century. It is a good book for those who do not wish to go into the subject in detail and is a good source of pictures and data for modelers.
