Britannia is just another possible future of great Britain XD

No, in the CG universe, Great Britian doesn't exist. What happens is that America looses the Revolution and are forever a colony of England. During the Napoleonic era, Napoleon successfully conquers England, forcing its leaders to flee to America, forming the Holy Britannian Empire. Thus Britain doesn't really exist in the same way it is today and it also means no country has tea-makers equipped in their armored tanks.
