During the late 1960's a number of European countries examined ways to replace their existing fleet of combat aircraft using next-generation design techniques. Several countries looked at variable geometry wing configurations as a means of making a plane perform well throughout a wider flight envelope.

In many respects, the Panther tank was viewed as the finest armored fighting vehicle of the Second World War. Based in large part upon the Soviet's highly successful T-34 medium tank, the PzKpfw V Ausfuhrung G (Type G) was built by several manufacturers including MAN, Daimler-Benz, and MNH.

The Lockheed Martin F-35 Lightning II is a fifth-generation, single-seat, single-engine, stealth-capable military strike fighter, a multirole aircraft that can perform close air support, tactical bombing, and air superiority fighter missions.

The M24 Chaffee - arguably the best light tank of World War II - was a fast, lightly armored vehicle with the ability to deliver relatively large caliber direct fire thanks to its excellent 75 mm M6 gun. More than 4,000 vehicles were produced by Cadillac and Massey-Harris from 1943-45.

In 1938, with the start of World War II looming, the Russian Automobile Co., GAZ, started the development and production of 4x4 vehicles for the Russian Army. Their first model was the GAZ 61, designed to fill the same needs as the Bantam BRC40 jeep built in Butler, PA by the Americans.

Early in 1943, orders were given to design a heavy, self-propelled anti-tank gun, which would mate a 12.8cm gun with a Tiger II chassis. On October 20th, 1943 a wooden mock-up of the enormous vehicle was shown to the OKH planners who authorized that a prototype be finished by April 1944.
