Can the Scout(tan) pass throught a wall with a closed door with its ability?
The ability says you can pass throught walls without doors, but it doesn't mention about walls with closed doors.
You could always ignore the door and pass through the wall, if you want to be literal
Though there IS a relevance inasmuch as the door would remain locked, barring other commandos. So he COULD deal with the door if it made sense for the party.
I read it as the ability to pass through walls, EVEN those without doors.
The rules are quite loose and don't cover every eventuality, but most are easy to interpret the intentions of the designer. There is the rules translation issue too.
