Hey Mitchifer,
The "Symbols of France" will appear on many of the ships in the carousel. These symbols function like the "first victory of the day" stars. You will be able to "knock" these Symbols of France in any battle mode except Training Room and Clan Battles.
Tier VI and lower you will get coal.
Tier VII to Tier X you will get Republic Tokens.
Remember you can only get this bonus one time during update 0.8.6.
Hey Edgecase,
The "Symbols of France" will work similar to the snowflakes event of the 0.7.12. patch around the holidays.
Hey Iron_Dog,
Tier VIII Japanese battleship Kii:
Armor of citadel deck increased from 22 to 32 mm.
After penetrating the armor belt of the Kii, shells with a caliber of 356 mm and more didn't ricochet against the thin armor of the citadel deck and penetrated it. To increase the survivability of the ship, the armor was increased from 22 to 32 mm.
I believe this is what you are looking for and it was announced in a previous Developer's Blog:
