Christie suspensionThe Christie suspension is a suspension system developed by American engineer J. Walter Christie for his tank designs. It allowed considerably longer movement than conventional leaf spring systems then in common use, which allowed his tanks to have considerably greater cross-country speed. The system was first introduced on his M1928 design, and used on all of his designs until his death in 1944. Christie advocated the use of lightweight tanks with long range and high speed, designed to penetrate enemy lines and attack their infrastructure and logistics capabilities.
TankA tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat.
TanketteA tankette is a tracked armoured fighting vehicle that resembles a small tank, roughly the size of a car. It is mainly intended for light infantry support and scouting. Colloquially it may also simply mean a small tank. Several countries built tankettes between the 1920s and 1940s, and some saw limited combat in the early phases of World War II. The vulnerability of their light armour, however, eventually led armies to abandon the concept with some exceptions such as the more modern German Wiesel (Weasel) series.
Tank destroyerA tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. As such, they are typically armed with a direct fire artillery gun, then called self-propelled anti-tank gun, or missile launcher, then called anti-tank missile carrier, and designed specifically to engage and destroy enemy tanks, often with limited operational capacities.
