Not entirely true...
First. planes themselves are not always swappable. IIRC, you cannot add missiles to a plane that has no variant with missiles in vanilla. Might be wrong though...
Anything with external missile launchers (Hawk, Kub/Buk, Harpon, etc.) also have swappable weapon models.
For helicopters, I hear some are swappable, and some are not. I think it depends on the unit, but I imagine that open missiles (not in tubes) might be.
For infantry, the weapons on their backs (MANPADS, AT launchers, etc.) can be changed, but not the weapons the soldiers are holding in their hands.
Feel free to correct me.
