The Business Insider:
The M1 Abrams tank has a reputation for being very hard to kill.
According to Tom Clancy’s book “Armored Cav,” in one instance an Abrams got stuck in the mud during Operation Desert Storm and was attacked by three T-72s tanks.
The Iraqi rounds bounced off – including one fired from less than 500 yards away. After the crew evacuated, a platoon of Abrams tanks then fired a bunch of rounds with one detonating the on-board ammo.
