M60A3 - Austrian Army

The M60 Patton is a main battle tank (MBT) introduced in December 1960. With the United States Army's deactivation of their last (M103) heavy tank battalion in 1963, the M60 became the Army's primary tank during the Cold War. Although developed from the M48 Patton, the M60 series was never officially classified as a Patton tank, but as a "product-improved descendant" of the Patton series. In March 1959, the tank was officially standardized as the 105 mm Gun Full Tracked Combat Tank M60.
The M60 underwent 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 U.S. and its Cold War allies, especially those in NATO, and remains in service throughout the world today, despite having been superseded by the M1 Abrams in the U.S. military. Egypt is currently the largest operator with 1,716 upgraded M60A3s, Turkey is second with 866 upgraded units in service, and Israel is third with over 700 units of Israeli variants.
