To Ryan - Having only been back at ASL for the last year myself, I think it is completely understandable that you missed the (Building) Control Rules. The rules for Victory Conditions occur at the end of chapter A (A26.0), after a series of RB sections dealing with "as needed" materials such as Cavalry, DC and FT, Nationality distinctions, etc. Most of the VC rules are of this type. It is natural when approaching ASL to absorb all of the need-to-know rules from Chapters A-D and to selectively skim other parts (like so much of chapter B!) until you play a scenario that employs them. Indeed, there are many rules that you will rarely find yourself needing at all (depending on your playing preferences), and one does want to get playing right away!
Forgive me if I am making poor assumptions here - and offering advice when none is asked for! - but I found it to be very useful to keep reading and rereading those first five chapters for the first few months after beginning to play again (even parts I don't need for my current game(s)). A pocket edition of the RB is great for this purpose. The entire RB continually cross-references and interconnects, and frequently the answer to one question lies in a very different part of the tome. But, after a fashion, you become fairly secure - beginning to feel confident of both what you do know, and what you will need to know better when the time arises.
