I headed over ther and grabbed a bunch of them. They'll be a great help for the base schemes.
What I really am hoping for is an identifying marking, like the USAFs bars and star or the RAF's roundel.
I don't know what the manual has in it, but I found a cheap copy of the Startegy Guide on Amazon, so I'll grab that and see what it's got.
If worse comes to worse, I'll just design something on my own.
