I have tried the mission numerous times now - and can never complete it.
It always ends with the me not getting the forth column ....

I don't think that I get the first three columns either but it says i do ....

Any tips on how to conquer this mission ?

Bonus info - I completed it ones - bur only because the game didn't end when I failed to kill the fourth column.

I have played "operation Uhthe-Thuum-QAI a couple of times now and wondered how to win...

I capture the node and kill everyone - and then nothing happens.,

I see now that there are no objectives on the map ... (shown to me).

Any clues how to fix that ?
