Hi!
Now I understand what did you mean for blue Russia....no problem for it.... if I remember correctly that faction was called White Russia opposed to the Reds....I'll research in the russian revolution history up to 1926....the time limit for DOF....
In the nation list I use the native language where possible....Kaiser Marine is done with Kaiserliche Marine from the start....as for other air force....
For the K.u.K. the navy section 'll be done if not managed from the navy like the....Kaiser Marine....
....if belonging to navy I'll add them as a separate service like historical reality....
About the dirigibles....I look at them this afternoon....there are about 30 of them in service with heer or navy....if I add each one it will be simple for missions and/or static campaign makers build missions with a specific one....but maybe in dynamic campaign building this can cause a mess if the game engine replace it if downed....I'll ask to those great guys a think about....and if they confirm my thoughts I'll have to add both kind of them: each specific and a generic....
