In 1963 West Germany and the United States signed an agreement to develop the best tank in the world - the MBT/KPz-70. Though by 1970 this project was stopped, West Germany used the components created for the MBT/KPz-70 to develop a new main battle tank - the Leopard 2. Since 1979, when the first Leopard 2 rolled off the production line, the Leopard 2 has undergone various modifications, and has been exported to various European countries. Enhanced by Osprey's signature colour plates and cutaway artwork, this book examines the development of the Leopard 2 from the first batch to its evolution into the improved Leopard 2 A5, detailing its features and variants.

The US Army requirement for a light utility helicopter was formulated after the Korean War. Bell's Model 204 design won a competition in 1955, and was given the military designation H-40, later renamed the HU-1 Iroquois. The original design called for a helicopter that could be used for transport, airborne battlefield command and control, medical evacuation, fire support co-ordination and search and rescue. Later its missions would be expanded to include troop insertion/extraction, armed escort and special operations. This title details all the technological background behind the development and use of the Huey " Slick" in Vietnam, as well as covering all the major uses that this transport aircraft was put to.
