I've been wondering about some of the Belles.
Six Warships are recognized for having fought in both World Wars and survived to this day.
The surviving vessels that hold the distinction of serving in both World Wars are the Medea, which served both the French Navy and Royal Navy, British Monitor HMS M33, the British Light Cruiser HMS Caroline, Greek Armored Cruiser Georgios Averof, the Drazki a Bulgarian torpedo boat and of course my beloved Texas dreadnought.
It seems to me they should be a bit older and more experienced and maybe make comments like "Well, back in '17..." They have been in large scale wars before.
