The quantum leap in the modernisation of the German Leopard 2A4 main battle tank was the upgrade to the A5 version. With this project the Leopard also received a radical new armour suite that significantly enhanced its protection level and changed its external appearance. All most recent Leopard 2 variants such as the 2A6 and the 2A7 are based on the Leopard 2A5. This publication, for the first time, grants an in-depth view into the development history, deployment and use as well as the groundbreaking technology of this major asset of the modern Panzertruppe. Two parts with a total of 144 pages illustrated with 320 colour photographs, 28 graphics and one five-perspective 1/35 scale drawing are a worthy documentation for Germany's most formidable fighting machine!
