Croix de Guerre? What mechanism was used to generate those? Will the Bosche be doing likewise? Where will it all end?
What was the actual basis for that award? Did the French award them per kills? Did every pilot get one at a pre-determined point, or was it random? If random, was it only after a certain level of achievement (ie, what's the cut-off point?)? If it's fixed I can add that in as-is, if random I can do a die-roll once the cut-off point has been exceeded per pilot (die-roll on each update, 20-sided die).
For the two you've already set in motion, I'll add smalls as and when you notify me, but any future ones should be done to a set mechanism, if one is decided upon.
