Dunno.
The Sherman remained service until the 1970s.
Had to have something going for it...

Sure did.

On a modern battlefield though, not so much.

As I recall, the Israelis successfully upgunned their Shermans to 90MM.

Seems like there was also an effort to upgun the American Shermans with the 90MM used in the Pershng, but it got nixed by Washington.
