FWWC & Alt Fire/Assault Resolution ORs

[Sir John Cope]

I recall reading somewhere that the reason the FWWC series does not include Alternative Indirect/Direct/Assault Resolution among its optional rules is that the series adopted "a version" of some (all?) of this set of ORs as part of its basic design.  

But, having searched the Design Notes, User and Main Program guides, this forum, and even the JTS product page, I am failing to locate the source for this recollection.  

Am I dreaming this, or can anyone confirm?
