The only one I know of right off is an M1A1 (IIRC) that rolled past an Iraqi tank which was sitting still (perhaps camouflaged and idled). It drifted in front of the Iraqi (T-72?) which fired into the rear door killing the M1A1 crew.
At least that’s what I recall reading waaaaaaay back.
One seems to recall hearing of an Abrams taken out by a new Russian missile called Kornet, IIRC, which is effective against the back side of an Abrams.
Can’t say where or when, though.
