M1 Abrams Main Battle Tank
As of 2018, M1 Abrams remains the main battle tank of the United States Army and Marine Corps. Given that its development began in the early 1980s, that’s nearly four decades of being king of the battlefield. There is also an export version used by armies worldwide, including Australia, Egypt, Iraq, Kuwait, and Saudi Arabia. The U.S. military has continued to make improvements and new additions to the tank throughout the years.
