Despite having already played a lot of XCOM 2, when I decided to start playing again, I was forced to do the tutorial (as the game was still installing at the time). During the tutorial, two squad members are scripted to die, since the tutorial forces you to make specific moves.
That said, there's an achievement called "The Untouchables" for beating the campaign on Commander+ without losing a single soldier. Will these two scripted deaths lock me out of that achievement for this run? That is, is it mandatory to skip the tutorial if I'm to attempt getting this achievement?
