Mischief Makers is the squad story focused on Viola, Simon, and Emmy.
This takes place on the same map as the second part of Chapter 3: Rangers in the Storm, with the differences of it being in daytime, and the northeast starting corner being inaccessible. In addition, there's grenadier shelters placed in the west part of the map, wooden walls placed around the southern most part of the map, and additional sandbags placed throughout.
Simon, Emmy, and Viola will start in the northeast part of the map and will work their way counterclockwise to defeat the opposing Federation team.
We will now begin the mock battle to rehabilitate your insubordinate troops
"Simon, Viola, and Emmy are to engage an opposing team, led by the squad leader. The program will be considered a success when all three of you work together to win."
Description: Defeat all enemy units to get the troublemakers through "rehabilitation" safely. The program will be deemed a failure if Simon, Viola, or Emmy is eliminated.
"That concludes the briefing. Now it's time for rehab."
The mission name is a reference to the movie Inglorious Basterds
