The German heavy tank destroyer Panzerjäger Tiger (P) (Sd.Kfz. 184) Ferdinand was based on the chassis of the Tiger (P) tank designed by Ferdinand Porsche. The vehicle was not accepted by army, but because 90 chassis have already been produced at the Nibelungenwerke plant, it was decided that they could be usefully developed. This is how the tank destroyer based on the Tiger (P) chassis was born.

The M3 vehicle was a thirteen-person armoured transporter that could be used to transport mechanized infantry or as an artillery tractor, ambulance, communications vehicle, etc. It was also used as a carrier for various types of guns. American factories producing M2 and M3 armoured personnel carriers were overloaded and could hardly meet orders for the army. That's why, in 1942, the International Harvester Company stated that it was capable of producing a combat vehicle similar to the M3, but due to some differences in the plant's machine park, not all components could be made in the same way. Therefore, it required slight changes in the design of the new transporter. Thus the Half-Track Personnel Carrier M5 was born, which was almost identical to the M3 version. The M5 versions were created primarily for the needs of foreign customers. They were used by the British Army, as well as Polish, Czech and "Free French" units. The British used them primarily to tow various types of anti-tank guns. These vehicles also found their way to the USSR under the Lend-Lease agreement. After the Second World War, they were also used by the Israeli army.

In the '30s, Americans began working on a modern vehicle for cavalry reconnaissance and artillery units in freshly formed armoured and motorized units. The American command became interested in French half-track vehicle designs. On their basis the American industry proposed its own solutions. In 1938, White Motor Company created a vehicle called T-7, which was a combination of the design of the M3 scout car and the T-9 half-track transporter. Year later, a version with a more powerful engine was prepared. The new car was designated T-14 and used mainly by artillery units. In 1940, the project was renamed M2 and put into production.

M3 General Lee - an American medium tank from World War II era, also used by the British army. In the US, known as Lee, in the United Kingdom as Grant. M3 tank was created as a result of the need to replace the obsolete M2 tank, which did not match the WWII battlefield. The serial production began in August 1941. The M3 tank had many components from the M2 light tank, including chassis, Wright R975 EC2 star engine and the shape of the combat compartment.
