By the way, choices had to be made for BAT modules to save slots and avoid too much mod planes duplicated ; the La-11 probably fits better with #JTW module as a post-World War 2 fighter. It is always possible to add the mod manually to #WAW if needed...
I had the same thought. In fact, not quite three years ago I downloaded and installed a "MiG Alley" campaign which, though originally designed for HSFX, had been modified for CUP by bergkamp. It begins with the player flying an La-11. The campaign in its same, "CUP" form now lives in my BAT mission (Campaign/RU) files, and it works perfectly well in BAT Linebacker. Here's a link to a thread containing an active Mediafire link for the campaign. The link is in reply #12:
