@Yavid:
CV = Aircraft Carriers
CVN = Aircraft Carriers Night Opperations (WW2 Area)
CVN = Aircraft Carriers Nuclear (modern)
DEI = Dutch East Indies
SS = Submarines (I’m assuming it’s for Submerible Ship)
Sealion = Operation Sealion (The German invasion of UK)
Barbarosa = Operation Barbarosa (The German invasion of USSR)
I’ve heard of people using Typhoon (The German mad dash to take Moscow)
and Blue (The German push into Southern Russia)
HMS = Her Majesty’s Ship
IJ = Imperial Japan
USSR = Russia
AB = Air Base
NB = Naval Base
Alot of Axis and Allies fans are either military buffs, history buffs or both so ship stuff like CV or DD or SS is used for ships alot and WW2 Operations get used for general strategies. Such as "The Western Allies (america and uk) need to d-day (do i need to say what this is) asap (as soon as possible) to help russia fight off Barbarosa.
The H in HMS was “His” for WW2.
Citadel(le) = Historically, it was the German codename for the Kursk offensive. In AA terms, it can (at least in my group) refer to an all out and luck dependant German offensive against Russia launched in hopes of turning the tables in games where the Russians have already survived the biggest of German pushes and are clearly starting to win. A failed Citadel usually marks the beginning of the end of the game.
