Half-tracks Of Germany
A half-track is a civilian or military vehicle with wheels at the front for steering and continuous tracks at the back to propel the vehicle and carry most of the load. A half-track combines the soft-ground traction of a tank with the handling of a wheeled vehicle. Performance The main advantage of a half-track over a fully-wheeled vehicle is that its tracks reduce the pressure on any given area of the ground by spreading the vehicle's weight over a larger area, giving it greater mobility over soft terrain like mud and snow. A further advantage is that it does not require either the complex steering mechanism of a fully tracked vehicle or skill in tracked steering, relying instead on a familiar steering wheel connected to its front wheels to direct the vehicle; maneuverability is augmented in some cases by track braking tied to the steering wheel. The main disadvantage is the increased maintenance to maintain track tension, and the reduced life span of tracks (up to 10,000&nb ...

Artillery
Artillery consists of ranged weapons that launch Ammunition, munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to Shell (projectile), shell-firing Field gun, guns, howitzers, and Mortar (weapon), mortars (collectively called ''barrel artillery'', ''cannon artil ...

Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a Trailer (vehicle), trailer or machinery such as that used in agriculture, mining or construction.
