Light tank

A light tank is a tank variant initially designed for rapid movement, and now primarily employed in the reconnaissance role, or in support of expeditionary forces where main battle tanks cannot be made available. Early light tanks were generally armed and armored similar to an armored car, but used tracks in order to provide better cross-country mobility.

The fast light tank was a major feature of the pre-WWII buildup, where it was expected they would be used to exploit breakthroughs in enemy lines created by slower, heavier tanks. Numerous small tank designs and "tankettes" were developed during this period and known under a variety of names, including the "combat car".

The light tank has been one of the few tank variants to survive the development of the main battle tank, and has seen use in a variety of roles including the support of light airborne or amphibious forces and reconnaissance. Modified IFVs are assuming these roles in many militaries due to their immediate availability, a cheaper alternative to developing and fielding a pure light tank.

The Leopard

The Leopard (Italian: Il Gattopardo) is a novel by Giuseppe Tomasi di Lampedusa that chronicles the changes in Sicilian life and society during the Risorgimento. Published posthumously in 1958 by Feltrinelli, after two rejections by the leading Italian publishing houses Mondadori and Einaudi, it became the top-selling novel in Italian history and is considered one of the most important novels in modern Italian literature. In 2012, The Observer named it as one of "The 10 best historical novels".

The novel was also made into an award-winning 1963 film of the same name, directed by Luchino Visconti and starring Burt Lancaster, Claudia Cardinale and Alain Delon.

The author

Tomasi was the last in a line of minor princes in Sicily, and he had long contemplated writing a historical novel based on his great-grandfather, Don Giulio Fabrizio Tomasi, another Prince of Lampedusa. After the Lampedusa palace was bombed and pillaged by Allied forces in World War II, Tomasi sank into a lengthy depression, and began to write Il Gattopardo as a way to combat it.

Tank

A tank is a large, heavily armoured fighting vehicle with tracks and a large tank gun that is designed for front-line combat. Modern tanks are mobile land weapon platforms, mounting a large-calibre cannon in a rotating gun turret. They combine this with heavy vehicle armour which provides protection for the crew, the vehicle's weapons, and its propulsion systems, and operational mobility, due to its use of tracks rather than wheels, which allows the tank to move over rugged terrain and be positioned on the battlefield in advantageous locations. These features enable the tank to perform well in a tactical situation: the combination of powerful weapons fire from their tank gun and their ability to resist enemy fire means the tank can take hold of and control an area and prevent other enemy vehicles from advancing. In both offensive and defensive roles, they are powerful units able to perform key primary tasks required of armoured units on the battlefield. The modern tank was the result of a century of development from the first primitive armoured vehicles, due to improvements in technology such as the internal combustion engine, which allowed the rapid movement of heavy armoured vehicles. As a result of these advances, tanks underwent tremendous shifts in capability during the World Wars of the 20th century.

Leopard

The leopard (Panthera pardus) is one of the five "big cats" in the genus Panthera. It is a member of the family Felidae with a wide range in regions of sub-Saharan Africa, West Asia, the Middle East, South and Southeast Asia to Siberia. Fossil records found in Italy suggest that in the Pleistocene it ranged as far as Europe.

Compared to other members of Felidae, the leopard has relatively short legs and a long body with a large skull. It is similar in appearance to the jaguar, but is smaller and more lightly built. Its fur is marked with rosettes similar to those of the jaguar, but the leopard's rosettes are smaller and more densely packed, and do not usually have central spots as the jaguar's do. Both leopards and jaguars that are melanistic are known as black panthers.

The leopard's success in the wild is due to its well camouflaged fur; its opportunistic hunting behaviour, broad diet, and strength to move heavy carcasses into trees; its ability to adapt to various habitats ranging from rainforest to steppe and including arid and montane areas; and to run at speeds up to 58 kilometres per hour (36 mph).

Light

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00 × 10⁻⁷ to 7.00 × 10⁻⁷ m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).

The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. Some species of animals generate their own light, a process called bioluminescence. For example, fireflies use light to locate mates, and vampire squids use it to hide themselves from prey.
