It would probably be more accurate to have the icon based on the
aircraft type and use the modifier to indicate the mission, but this
will do for now (I also might have that backwards, I can't find the
guidance because it's in STANAG 1241 which isn't free).
I also increased the icon size a bit in the UI because the longest icon
text ("SEAD") was hard to read.
