Information: - The 7.5 cm KwK 42 L / 70 ( from 7.5 cm Kampfwagenkanone 42 L / 70 ) was a 7.5 cm calibre German tank gun developed and built by Rheinmetall - Borsig AG in Unterlu during the Second World War . The gun was used to equip the SdKfz.171 Panther medium tank and the SdKfz.162 / 1 Jagdpanzer IV / 70 ( A ) / ( V ) tank destroyer . When mounted on a tank destroyer it was designated as the 7.5 cm Pak 42 ( 7.5 cm Panzerabwehrkanone 42 ) . - The "Panzerkampfwagen" IV (PzKpfw IV), commonly known as the Panzer IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161. - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - Medium tank is a classification of tanks, particularly prevalent during World War II which represented a compromise between the mobility oriented light tanks and the protection and armour protection oriented heavy tanks. The most widely produced, cost effective and successful tanks of World War II (the Soviet T-34, the American Sherman tank, the Japanese Type 97 and the German Panzer IV) were all medium tank designs, and the success of the concept would later lead to the development of later generations of medium tanks such as the Chieftain. Many of the medium tanks lines became what are called main battle tank in most countries. - The T-34 was a Soviet medium tank that had a profound and lasting effect on the field of tank design. Although its armour and armament were surpassed later in the war, it has often been credited as the most effective, efficient and influential tank design of the Second World War. At its introduction, the T-34 possessed an unprecedented combination of firepower, mobility, protection and ruggedness. Its 76.2mm (3in) high-velocity tank gun provided a substantial increase in firepower over any of its contemporaries; its heavy sloped armour was difficult to penetrate by most contemporary anti-tank weapons. When first encountered in 1941, the German tank general von Kleist called it "the finest tank in the world" and Heinz Guderian confirmed the T-34's "vast superiority" over existing German armour of the period.

Information: - The Naraka dynasty is a mythological dynasty of Assam in Northeast India that has been sourced to mentions in epics such as the "Ramayana", the "Mahabharata", the "Kalika Purana", the "Yogini Tantra" and local lore.
