solaris turrets are considered free for all ( by the rule )
so are mortars, razors, cerberus, inferno ( cap version ) - that might one time change though, depending on how far the roleplay is carried concerning capship weapons.
solaris ( order )
mortars ( order )
razors ( errrrr - no idea? popped up in space )
cerberus ( rheinland )
inferno ( outcast )
the point is that these weapons are considered "necessary" for a balanced equipped capital ship. its somewhat overrated - they are useful, but the basic turrets do the job just as good - most of the time ( when facing another ship with only basic turrets:laugh::laugh:)
