Welcome to the World of WOFF, CodeRed.
I guess with "mission mods" you mean any aids being left out of the A-category of this DiD Campaign?
Well, they are LABELS, TAC (kind of radar), additional gauges and other aides,
and they simply don't belong to a 100% WW1-simulating flying, which the A-category is meant to be.

Are you flying WOFF already, or just visiting?
