So now that Interstellar Operations includes Inner Sphere at War (or "ISW"), is the official short-hand for this book "1SW"?
Also, I noticed that the list of former SLDF units which remained behind did not include the Star League Expeditionary Brigade, nor their affiliated Avatar-class WarShip SLS Pioneer.
Is the information in ISP3 concerning their ultimate fate considered to be "official", or does it have a qualifier due to it being in an "Interstellar Players" volume? And either way, would they not count for the list in this book anyway, since the SLEB was seemingly disbanded prior to the Exodus?
(Which might raise a question as to how so many of its former members, plus their dependents, managed to slip away with their old WarShip. Or how long it seemingly took for them to make it as far as Paran...)
