Complementing the well-established and successful "Polish Wings" series on aircraft of the Polish Air Force, this book is the second in a series on Polish army vehicles. It tells the story of four major tanks of British origin used by the Polish army in the 1930s, some still in use at the time of the German invasion. Training and operations with these tanks are described and illustrated, with many photos and full color artwork. Color schemes and markings are described and illustrated.
