What is the name of the movie that features army soldiers who find a tank buried in the sand which they use to drive across the desert?

it sounds like 'three kings', perhaps?

I am pretty sure the film you mean is "The Steel Lady" from 1953

Yes, it was "The Steel Lady."

Yul Brynner starred in a movie about soldiers driving a tank in the desert but I can't remember the name of it something like Death Race or Death Chase or something.

That movie was Death Race. I answered another question about it, but Yul Brynner was not in that particular movie. The question says they were soldiers who find the tank, but they were oil prospectors.
