I think it would be easy to implement a display tab in your stats screen where you are shown your win/lose ratio per division used - and even the total Killed / Lost units in all the games of a specific division.
This could go even further with comparisons of specific equipment kills and loses, showing that for example the player has a weakness in handling AT etc.
