Main battle tank

A main battle tank (MBT), also known as a battle tank or universal tank or simply tank, is a <a href="/facts/Tank/CwQLRQsy">tank</a> that fills the role of armour-protected <a href="/facts/Direct_fire/Nu2ocjac">direct fire</a> and maneuver in many modern armies. <a href="/facts/Cold_War/spJdJQ3q">Cold War</a>-era development of more powerful engines, better suspension systems and lighter <a href="/facts/Composite_armour/7ChAyoFA">composite armour</a> allowed for the design of a tank that had the firepower of a <a href="/facts/Super-heavy_tank/q8hBsaKX">super-heavy tank</a>, the armour protection of a <a href="/facts/Heavy_tank/yCTIP18N">heavy tank</a>, and the mobility of a <a href="/facts/Light_tank/9E5NwqS2">light tank</a>, in a package with the weight of a <a href="/facts/Medium_tank/0MlXahKV">medium tank</a>. The first designated MBT was the British <a href="/facts/Chieftain_(tank)/uq1Vlhj1">Chieftain tank</a>, which during its development in the 1950s was re-designed as an MBT. Throughout the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of <a href="/facts/Armoured_fighting_vehicle/RGHj9Y1r">armoured fighting vehicles</a>.
Main battle tanks are a key component of modern armies. Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of <a href="/facts/Infantry/QAHDDQtk">infantry</a>, who may accompany the tanks in <a href="/facts/Infantry_fighting_vehicle/MNr3khds">infantry fighting vehicles</a>. They are also often supported by <a href="/facts/Surveillance_aircraft/9ae9ulxs">surveillance</a> or <a href="/facts/Ground-attack_aircraft/Rkc7Ft5I">ground-attack aircraft</a>. The average weight of MBTs varies from country to country. The average weight of Western MBTs is usually greater than that of Russian or Chinese MBTs.
