Say I have a Violator, and I want to replace the Apollo guided MRM 10s with Artemis IV guided SRM 6s. Are the guidance systems considered part of the weapon itself (making this a class A refit), or are they considered equipment (which I believe would be class C here). Similarly, would removing the MRM 10s for Streak SRM 6s be a class A (swap of weapons of the same type) or class C (removal of non-weapon equipment)?
