(Answered) CO - Refits - CASE automatic installation on Clan Mechs

[TimberwolfD]

I saw this question regarding CASE in mixed tech units (https://bg.battletech.com/forums/index.php?topic=82213.0) and it made me curious about the impact of automatic CASE on refits.

1. Since adding CASE to a location that did not have it is a Class D refit, wouldn't any clan internal structure tech base unit automatically require a Class D refit to mount ammunition or gauss weapons that trigger the automatic addition of CASE?
2. In the case of a refit, can CASE be left in place even without ammo or explosive equipment to "cause" its install? If no, what is the appropriate class of refit to remove CASE?

If the unit is of the clan tech base, adding CASE is not a change at all: you just get it if you add weapons that need ammunition.  But it isn't there in some sort of phantom sense in that it only triggers when ammo-dependent weapons are added.
