The gods of irony got together with the gods of gaming after my recent gripe about having to do and redo things in MGSV:TPP:
Some missions have mutually-exclusive objectives – I’m looking at you, Backup, Back Down – so may require more
Well, I played through the “Extreme” version of Back Up, Back Down to do the additional objectives, and the team searching for the prisoner got there, stood around him and then… very kindly didn’t execute him.
So I ran up, stunned them all with a non-lethal assault rifle and fultoned him out! All optional objectives complete.
