T-72
The T-72 is a family of Soviet/Russian main battle tanks that entered production in 1969. The T-72 was a development of the T-64, which was troubled by high costs and its reliance on immature developmental technology. About 25,000 T-72 tanks have been built, and refurbishment has enabled many to remain in service for decades. It has been widely exported and has seen service in 40 countries and in numerous conflicts. The T-90 introduced in 1992 is a development of the T-72B; production and development of various modernized T-72 models continues today. Development Development from the T-64 The T-72 was a product of a rivalry between design teams. Morozov KB was led by Alexander Morozov in Kharkiv. Uralvagon KB was led by Leonid Kartsev in Nizhny Tagil. To improve on the T-62, two designs based on the tank were tested in 1964: Nizhny Tagil's Object 167 (T-62B) and Kharkiv's Object 434. Ob. 434 was a technically ambitious prototype. Under the direction of Morozov in Kharkiv, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-72 Operators And Variants
The T-72 is a Soviet-designed main battle tank that entered production in 1971. It replaced the T-54/55 series as the workhorse of Soviet tank forces (while the T-64 and T-80 served as the Soviet high-technology tanks). In front-line Russian service, T-72s are being upgraded or augmented by the T-90 (itself, a modernized version of the T-72B). The T-72 has been exported and produced in many countries.

Composite Armour
Composite armour is a type of vehicle armour consisting of layers of different material such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles. HEAT had posed a serious threat to armoured vehicles since its introduction in World War II. Lightweight and small, HEAT projectiles could nevertheless penetrate hundreds of millimetres of the most resistant steel armours. The capability of most materials for defeating HEAT follows the "density law", which states that the penetration of shaped charge jets is proportional to the square root of the shaped charge liner den ...

2003 Invasion Of Iraq
The 2003 invasion of Iraq was a United States-led invasion of the Republic of Iraq and the first stage of the Iraq War. The invasion phase began on 19 March 2003 (air) and 20 March 2003 (ground) and lasted just over one month, including 26 days of major combat operations, in which a combined force of troops from the United States, the United Kingdom, Australia, and Poland invaded Iraq. Twenty-two days after the first day of the invasion, the capital city of Baghdad was captured by Coalition forces on 9 April 2003 after the six-day-long Battle of Baghdad. This early stage of the war formally ended on 1 May 2003 when U.S. President George W. Bush declared the "end of major combat operations" in his Mission Accomplished speech, after which the Coalition Provisional Authority (CPA) was established as the first of several successive transitional governments leading up to the first Iraqi parliamentary election in January 2005. U.S. military forces later remained in Iraq u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolled Homogeneous Armour
Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks. After World War II, it began to fall out of use on main battle tanks and other armoured fighting vehicles intended to see front-line combat as new anti-tank weapon technologies were developed which were capable of relatively easily penetrating rolled homogeneous armour plating even of significant thickness. Today, the term is primarily used as a unit of measurement of the protection offered by armour on a vehicle (often composed of materials that may not actually contain steel, or even contain any metals) in equivalent ''millimetres of RHA'', referring to the thickness of RHA that would provide the same protection. Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protect ...

2022 Russian Invasion Of Ukraine
On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. An estimated 8 million Ukrainians were displaced within their country by late May and 7.8 million fled the country by 8 November 2022, while Russia, within five weeks of the invasion, experienced its greatest emigration since the 1917 October Revolution. Following the 2014 Ukrainian Revolution, Russia annexed Crimea, and Russian-backed paramilitaries seized part of the Donbas region of south-eastern Ukraine, which consists of Luhansk and Donetsk oblasts, sparking a regional war. In March 2021, Russia began a large military build-up along its border with Ukraine, eventually amassing up to 190,000 troops and their equipment. Despite the build-up, denials of plans to invade or attack Ukraine were issued by various Russian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tigray War
The Tigray War; ; . was an armed conflict that lasted from 3 November 2020 to 3 November 2022. The war was primarily fought in the Tigray Region of Ethiopia between the Ethiopian federal government and Eritrea on one side, and the Tigray People's Liberation Front (TPLF) on the other. After years of increased tensions and hostilities between the TPLF and the governments of Ethiopia and Eritrea, fighting began when Tigrayan security forces attacked the Northern Command headquarters of the Ethiopian National Defense Force (ENDF), alongside a number of other bases in Tigray. The ENDF counterattacked from the south – while Eritrean Defence Forces (EDF) began launching attacks from the north – which Prime Minister Abiy Ahmed described as "law enforcement operations." Federal allied forces captured Mekelle, the capital of the Tigray Region, on 28 November, after which Abiy declared the operation "over." However, the Tigray government stated soon afterwards that it would continu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2020 Nagorno-Karabakh War
The Second Nagorno-Karabakh War was an armed conflict in 2020 that took place in the disputed region of Nagorno-Karabakh and the surrounding territories. It was a major escalation of an unresolved conflict over the region, involving Azerbaijan, Armenia and the self-declared Armenian breakaway state of Artsakh. The war lasted for more than a month and resulted in Azerbaijani victory, with Armenia ceding the territories it had occupied in 1994 surrounding Nagorno-Karabakh. The defeat ignited anti-government protests in Armenia. Post-war skirmishes continued in the region, including substantial clashes in 2022. Fighting began on the morning of 27 September, with an Azerbaijani offensive along the line of contact established in the aftermath of the First Nagorno-Karabakh War (1988–1994). Clashes were particularly intense in the less mountainous districts of southern Nagorno-Karabakh. Turkey provided military support to Azerbaijan, although the extent of this support has ...

2016 Nagorno-Karabakh Clashes
The 2016 Nagorno-Karabakh conflict, also known as the Four-Day War,, IPA: ʰɑroɾjɑ pɑtɛɾɑzm az, Dördgünlük müharibə April War,; or April clashes, began along the Nagorno-Karabakh line of contact on 1 April 2016 with the Artsakh Defence Army, backed by the Armenian Armed Forces on one side and the Azerbaijani Armed Forces on the other. The clashes occurred in a region that is disputed between the self-proclaimed Republic of Artsakh and the Republic of Azerbaijan. The region includes the former Soviet Nagorno-Karabakh Autonomous Oblast and surrounding areas, which are integral part of the Republic of Artsakh according to its Constitution. Azerbaijan claimed to prevent purported continuous Armenian shelling of civilian areas in Azerbaijan and started a military operation for this purpose. However, there was no evidence of Armenian shelling. Until the 2020 Nagorno-Karabakh war, the clashes were the worst since the 1994 ceasefire agreement signed by Artsakh, Azerb ...

Boko Haram Insurgency
The Boko Haram insurgency began in July 2009, when the militant Islamist and jihadist rebel group Boko Haram started an armed rebellion against the government of Nigeria. The conflict is taking place within the context of long-standing issues of religious violence between Nigeria's Muslim and Christian communities, and the insurgents' ultimate aim is to establish an Islamic state in the region. Boko Haram's initial uprising failed, and its leader Mohammed Yusuf was killed by the Nigerian government. He began the group in the year 2002, with a view of opposing western education with his followers. He was arrested at his parent's inlaws house by the Nigerian Military and subsequently handed over to the Nigerian police. He was survived by four wives and 12 children one of which was Abu Musab al-Barnawi who in the year 2016 wanted to lead the group. The movement consequently fractured into autonomous groups and started an insurgency, though rebel commander Abubakar Shekau ...

War In Iraq (2013–2017)
The War in Iraq was an armed conflict between Iraq and its allies and the Islamic State (also known as ISIS or ISIL) which began in 2013 and ended in December 2017. Following December 2013, the insurgency escalated into full-scale guerrilla warfare following clashes in the cities of Ramadi and Fallujah in parts of western Iraq, and culminated in the Islamic State offensive into Iraq in June 2014, which lead to the capture of the cities of Mosul, Tikrit and other cities in western and northern Iraq by the Islamic State. Between 4–9 June 2014, the city of Mosul was attacked and later fell; following this, Prime Minister Nuri al-Maliki called for a national state of emergency on 10 June. However, despite the security crisis, Iraq's parliament did not allow Maliki to declare a state of emergency; many legislators boycotted the session because they opposed expanding the prime minister's powers. Ali Ghaidan, a former military commander in Mosul, accused al-Maliki of being th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russo-Ukrainian War
The Russo-Ukrainian War; uk, російсько-українська війна, rosiisko-ukrainska viina. has been ongoing between Russia (alongside Russian separatists in Ukraine) and Ukraine since February 2014. Following Ukraine's Revolution of Dignity, Russia annexed Crimea from Ukraine and supported pro-Russian separatists in the war in Donbas against Ukrainian government forces; fighting for the first eight years of the conflict also included naval incidents, cyberwarfare, and heightened political tensions. In February 2022, the conflict saw a major escalation as Russia launched a full-scale invasion of Ukraine. In early 2014, pro-Russian Ukrainian president Viktor Yanukovych was ousted from office as a result of the pro-European Euromaidan and the Revolution of Dignity. Shortly after Yanukovych's overthrow and exile to Russia, pro-Russian unrest erupted in Ukraine's eastern and southern regions. Simultaneously, unmarked Russian troops moved into Ukraine's ...
