Force
From Supremacy Wiki
Force pass
This button, or pop-up allows any player to move the game along once the deadline has been passed (Force pass). Players who have not placed their orders will either pass or use default orders (for Set up and Pay Salaries).
When Force Pass is applied, play will move to the next player - so it is possible to lose your entire turn in one force.
When a player is force passed 3 times in row without logging back in they are declared missing in action (MIA).
