The Saab 37 Viggen was designed to a Swedish air force requirement for an integrated weapon system with high performance, great versatility, and STOL capability. It was intended to replace the Saab 32 Lansen attack plane and the Saab 35 Draken fighter. To meet the requirements of a multi-roll aircraft, Saab came up with a radical configuration for the day. The design used a conventional low-set delta wing extending from mid-fuselage to tail pipe, with small clipped canard wings mounted forward of the main wings and above the intakes. This single-seat aircraft was powered by a single license-built version of the Pratt & Whitney JT8D engine equipped with a thrust-reverser. This innovative design package created a plane capable of Mach 2 at high altitude and Mach 1 at low altitude while maintaining short-field takeoff and landing capabilities. A total of 329 Viggens were built, and from 1970 to 1990 they were the backbone of Sweden's air defense.

Osprey Publishing has a series known as “General Military” which has one-off books on different topics. This one is dedicated to the Tiger tank, although reading the book also provides a good insight on armored vehicle operations, as it includes descriptions of how the Tiger tanks worked together with Panzer III and half-track armored carrier personnel.

The book is divided into nine chapters. The first three chapters (Development, Organization, Mobility) basically evaluate the tank’s performance as a vehicle and how it was used in combination with other AFV. The following three chapters (Firepower, Armor, Combat), cover the combat experience of the tank, with specifics sections for combat in each front (Western, Eastern, and Africa), while the final three (Maintenance, Under Fire, Conclusions) cover different aspects from the recovery of those vehicles to how they performed in the last years of the war, facing upgraded allied armor vehicles.

Although the He-111 was designed supposedly as a civil transport prototype capable of carrying 10 passengers and mail, its main purpose was of a military nature. It first flew in 1935. Several modifications were made to improve performance. A major change was replacing the two 660-hp BMW engines with the 1,000 hp Daimler Benz DB 600A engines, which significantly improved performance. The He-111 cut its fighting teeth in the Spanish Civil War, serving with the Condor Legion where it was very successful. That success continued in the early days of World War II. Germany overran several countries with its Blitzkrieg tactics, staring the Ju-87 and the He-111. Its success faded with the onset of the Battle of Britain when the lightly armed He 111 encountered the fast Spitfires and Hurricanes. By the time Hitler lost this battle, he was already planning Operation Barbarossa, the invasion of the Soviet Union. The He 111 again found success on the Russian Front.
