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 battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, and thus be more flexibly positioned at advantageous locations on the battlefield. These features enable the tank to perform in a variety of intense combat situations, simultaneously both offensively (with direct fire from their powerful main gun) and defensively (as fire support and defilade for friendly troops due to the near invulnerability to common infantry small arms and good resistance against heavier weapons, although anti-tank weapons used in 2022, some of them man-portable, have demonstrated the ability to destroy older generations of tanks with single shots), all while maintaining the mobility needed to exploit changing tactical situations. Fully integrating tanks into modern military forces spawned a new era of combat called armoured warfare. Until the invention of the main battle tank, tanks were typically categorized either by weight class (light, medium, heavy or superheavy tanks) or doctrinal purpose (breakthrough-, cavalry-, infantry-, cruiser-, or reconnaissance tanks). Some are larger and more thickly armoured and with large guns, while others are smaller, lightly armoured, and equipped with a smaller caliber and lighter gun. These smaller tanks move over terrain with speed and agility and can perform a reconnaissance role in addition to engaging hostile targets. The smaller, faster tank would not normally engage in battle with a larger, heavily armoured tank, except during a surprise flanking manoeuvre.
Think tankA think tank, or public policy institute, is a research institute that performs research and advocacy concerning topics such as social policy, political strategy, economics, military, technology, and culture. Most think tanks are non-governmental organizations, but some are semi-autonomous agencies within a government, and some are associated with particular political parties, businesses, or the military. Think tanks are often funded by individual donations, with many also accepting government grants. Think tanks publish articles and studies, and sometimes draft legislation on particular matters of policy or society. This information is then used by governments, businesses, media organizations, social movements, or other interest groups. Think tanks range from those associated with highly academic or scholarly activities to those that are overtly ideological and pushing for particular policies, with a wide range among them in terms of the quality of their research. Later generations of think tanks have tended to be more ideologically oriented. Modern think tanks began as a phenomenon in the United Kingdom in the 19th and early 20th centuries, with most of the rest being established in other English-speaking countries. Before 1945, they focused on the economic issues associated with industrialization and urbanization. During the Cold War, many more American and other Western think tanks were established, which often guided government Cold War policy. Since 1991, more think tanks have been established in non-Western parts of the world. Over half of all think tanks that exist today were established after 1980. As of 2023, there are more than 11,000 think tanks globally.
Panther tankThe Panther tank, officially Panzerkampfwagen V Panther (abbreviated Pz.Kpfw. V) with ordnance inventory designation: Sd.Kfz. 171, is a German medium tank of World War II. It was used in most European theatres of World War II from mid-1943 to the end of the war in May 1945. The Panther was intended to counter the Soviet T-34 medium tank and to replace the Panzer III and Panzer IV. Nevertheless, it served alongside the Panzer IV and the heavier Tiger I until the end of the war. While having essentially the same Maybach V12 petrol (690 hp) engine as the Tiger I, the Panther had better gun penetration, was lighter and faster, and could traverse rough terrain better than the Tiger I. The trade-off was weaker side armour, which made it vulnerable to flanking fire, and a weaker high explosive shell. The Panther proved to be effective in open country and long-range engagements. The Panther had excellent firepower, protection and mobility, though early variants suffered from reliability issues. The Panther was far cheaper to produce than the Tiger I. Key elements of the Panther design, such as its armour, transmission, and final drive, were simplifications made to improve production rates and address raw material shortages. The Panther was rushed into combat at the Battle of Kursk in the summer of 1943 despite numerous unresolved technical problems, leading to high losses due to mechanical failures. Most design flaws were rectified by late 1943 and early 1944, though the Allied bombing of production plants in Germany, increasing shortages of high-quality alloys for critical components, shortage of fuel and training space, and the declining quality of crews all impacted the tank's effectiveness. Though officially classified as a medium tank, at 44.8 metric tons the Panther was closer in weight to contemporary foreign heavy tanks. The Panther's weight caused logistical problems, such as an inability to cross certain bridges; otherwise, the tank had a very high power-to-weight ratio which made it highly mobile. The naming of Panther production variants did not follow alphabetical order, unlike most German tanks – the initial variant, Panther "D" (Ausf. D), was followed by "A" and "G" variants.
M60 tankThe M60 is an American second-generation main battle tank (MBT). It was officially standardized as the Tank, Combat, Full Tracked: 105-mm Gun, M60 in March 1959. Although developed from the M48 Patton, the M60 tank series was never officially christened as a Patton tank. It has been called a "product-improved descendant" of the Patton tank's design. The design similarities are evident comparing the original version of the M60 and the M48A2. The United States fully committed to the MBT doctrine in 1963, when the Marine Corps retired the last (M103) heavy tank battalion. The M60 tank series became the American primary main battle tank during the Cold War, reaching a production total of 15,000 M60s. Hull production ended in 1983, but 5,400 older models were converted to the M60A3 variant ending in 1990. The M60 reached operational capability upon fielding to US Army European units beginning in December 1960. The first combat use of the M60 was by Israel during the 1973 Yom Kippur War, where it saw service under the "Magach 6" designation, performing well in combat against comparable tanks such as the T-62. The Israelis again used the M60 during the 1982 Lebanon War, equipped with upgrades such as explosive reactive armor to defend against guided missiles that proved very effective at destroying tanks. The M60 also saw use in 1983 during Operation Urgent Fury, supporting US Marines in an amphibious assault on Grenada. M60s delivered to Iran also served in the Iran–Iraq War. The United States' largest deployment of M60s was in the 1991 Gulf War, where the US Marines equipped with M60A1s effectively defeated Iraqi armored forces, including T-72 tanks. The United States retired the M60 from front-line combat after Operation Desert Storm, with the last tanks being retired from National Guard service in 1997. M60-series vehicles continue in front-line service with a number of countries' militaries, though most of these have been highly modified and had their firepower, mobility, and protection upgraded to increase their combat effectiveness on the modern battlefield. The M60 has undergone many updates over its service life. The interior layout, based on the design of the M48, provided ample room for updates and improvements, extending the vehicle's service life for over four decades. It was widely used by the US and its Cold War allies, especially those in NATO, and remains in service throughout the world, despite having been superseded by the M1 Abrams in the US military. The tank's hull was the basis for a wide variety of Prototype, utility, and support vehicles such as armored recovery vehicles, bridge layers and combat engineering vehicles. As of 2015, Egypt is the largest operator with 1,716 upgraded M60A3s, Turkey is second with 866 upgraded units in service, and Saudi Arabia is third with over 650 units.

Tank ManThe Tank Man (also known as the Unknown Protester or Unknown Rebel) is the nickname given to an unidentified individual, presumed to be a Chinese man, who stood in front of a column of Type 59 tanks leaving Tiananmen Square in Beijing on June 5, 1989. On the previous day, the government of China cleared the square of protesting students after six weeks of standoff, in the process killing hundreds or even thousands of people mostly in other parts of Beijing. As the lead tank maneuvered to pass by the man, he repeatedly shifted his position in order to obstruct the tank's attempted path around him, and forced the tanks to halt to avoid running him over; the man then climbed on top of the tank where the PLA soldiers talked to the man. The incident was filmed and shared to a worldwide audience. Internationally, it is considered one of the most iconic images of all time. Inside China, the image and the accompanying events are subject to censorship. Many documentaries and related exhibitions about the June 4th Tiananmen Square Incident mention the incident of protesters blocking tanks, and regard the "Tank Man" as an iconic symbol of the incident. It has long been circulated that the protester's name is "Wang Weilin". The name first appeared in the British Sunday Express in its English pinyin "Wang Weilin". However, Tank Man's exact identity and whereabouts remain unknown, and different news media have different names for the protester. The PBS program Frontline produced a documentary about the incident in 2006. The news documentary Flying the Flag of the Republic produced by the Chinese military film studio August First Film Studio described the man as a "gangster who tried to stop a car with his bare hands". Western society calls this man "Tank Man" or "Unknown Protester". In April 1998, Time magazine named "The Unknown Rebel" one of the 100 most influential people of the 20th century. In 2003, Life magazine published a book called “100 Photos That Changed the World” which also included photos of people blocking a tank convoy. Although the images are regarded as an iconic symbol of the 20th century, the Chinese government prohibits the circulation of related images on the Internet, which means that most Chinese people are not aware of them. In September 2019, one of the photographers of such photos, Charlie Cole, died in Bali, Indonesia. There is no reliable information about the identity or fate of Tank Man; the story of the tank crew is also unknown. At least one witness has stated that Tank Man was not the only person to have blocked the tanks during the protest.
