About claiming system, I wish that (in order of importance, for me)

-1/ All claims should be recorded, even the erroneous ones
-2/ Possibility to give different claims different witnesses
-3/ Position of the claim should be taken in consideration, not only witness : an aircraft shot down 10 km in our lines should be easily accorded, even without flying witnesses. Maybe adding time to making the thing harder (I think what really counts when claiming was type, hour and place, witnesses were only there to back up your words. But I think the map is not enough detailled to include place).

Another little thing, in french, the Adjutant rank doesn't exist, the Adjudant, yes!
