Spring RTS Engine

appologies for all the novice posts. heh im determined to do this right.

anyway, does
group_landair (in XTAv9.1 atleast)
refer to flying units?

or something like idle (landed) air units?

how would i refer to all air units?

thanks

I didnt even know this tag existed, so id like to know as well.

It's not a tag, it's a category or armor type.
