The point I was trying to convey was that I'm okay with the backstory, mostly - the extent of my suggestion was to tweak the description a bit to account for Kido Corps being rolled into R&D, as well as remove the notion of numbered Divisions so we don't actually have to worry how many Divisions there might have been in the past.

It's not a big deal if there once were 13 Divisions - as terry noted, that's just needlessly many for the actual game. But if you really want to call the Divisions "6th" and "11th" in their history and unofficially in the game, I guess it can do. For the purposes of the registry, though, I'd ask you to call Sawada "Vice-Captain of the Assault Division" there (etc.).
