As Stu Leaders are very easily spotted, there's a few peculiarities with Leaders who are spotted when there's still some unspotted units in the same hex.

And here's how the visibility die rolls presented them to hostiles:



The spotted Stu Leader: he was killed right away. The ATG in same hex remain unspotted, unhurt.




I massed a lot of tanks to kill the visible Foot Leader. However it took me two scenario turns to kill him with forces available.

Second turn, second firing round: Success! These leaders never retreat unless they retreat with a friendly unit fired at. When they are the sole targets in a hex with unspotted other units, they stay until they die.



Just to prove there was another unit there as well, who was not spotted at any time, nor harmed:
