Could I add an air brigade for infantry?

[vladimir]

I hope to add a new type of sub-unit for infantry. I write it to unit-names, industry-inventions, and db/unit/airplane.txt. But I don't know how to add an unit picture. And how to valid for Victoria?

Keep us posted, it sounds like a really good idea!

Does any one knows the path and file name of pictures of add-brigade?
