Donut's name for the capstone action that follows the four offensives of Operation Ruin.
In his 25th-edition Cookbook note, Carl writes that Operation Ruin consists of four separate offensives, followed by what Donut calls the "Coup De War Crime." The four offensives kick off simultaneously with multiple coordinated prongs each, and if everything goes to plan the whole thing — capstone included — should be done in under seven hours.
Carl deliberately declines to spell out the details in a single post, comparing the attempt to explaining the Iron Tangle without a map, and instead limits himself to describing only his own tasks for the day.
The finishing blow planned to follow the four simultaneous offensives.
