I believe this discussion really is appropriate when talking about a dominant power vs a non-peer adversary, as we'd find in the most recent SEAL operation in Yemen. There, we had Senator McCain of Arizona decrying the raid as a failure using the following language: "When you lose a $75 million airplane and, more importantly, an American life is lost and wounded I don't believe you can call it a success...”
Collins, Eliza, USA Today 9 Feb 2017.
So, I'm thinking in game terms, can losses be expressed as a ratio against the force value.
FL/FV
Where, FL is force losses and FV is the force value. The FL then would be determined by FV
a - FV
b. Such that, FV
a is the initial force value at start of battle and the FV
b is the force value at end of game.
(FVa-FVb)/FVa
Now, if we could evaluate the ratio in an expression.
if (FVa-FVb)/FVa < 4%
We could say, for example that this battle earned (in jp10's language) "global acclaim."
