Allies (british, French side)
Britain, France, Russia & the US are common to the Allies in both WW1 & WW2. They are opposed by Germany in both wars. In WW1 Italy & Japan were both on the side of the Allies, in WW2 they were on Germanys' side. Turkey was on the side of Germany in WW1 & Neutral in WW2. Austria/Hungary was on the side of Germany in WW1 & were also on Germanys' side in WW2, (although it might be said by force rather than choice.) although they were then 2 separate countries.
