After each mission, you will be shown how many Carnage Points you
scored (one for each enemy unit and structure destroyed), and how
successfully the Primary, and if present, Secondary objectives were
completed. You might receive bonus Carnage Points for flying weaker
helicopters without Wingmen as support. Note that Carnage Points have
no bearing on whether or not you are victorious in an Operation, your Mission
Success Rate determines whether you win or lose in the end. Carnage
Points are simply an indicator of your destructive abilities in combat,
and will be recorded on the High Score Table along with your Success
Rate for posterity.
If the operation is over (either because you played to the end, lost
your base, or were killed in action) you'll be shown an ending screen
and then the high score table for the operation. If you survived till
the end and your Mission Success Rate was 80% or higher, you'll get to
see the winning screen for the operation. Between 70% and 79% is a
stalemate, and less than 70% is a defeat.
