While I have picked up (much to CaptainPMM for helping me out!) where squad loadouts are, armor/hp and the like are on the EBPS, however specific Squad interactions (Naming in the UI, abilities, experience, etc.) are in the SBPS, I have but one question:

How DO you make a custom unit? I also seem to have screwed myself up somewhere. As my unit appears in the building I want it to be built. (The infantry HQ for the US) however when I click to build it, it 'resets' like it was canceled. it shows up in the queue but disappears quickly.
(I set the squad limit to '1', but I'd like to know how to set it to a ridiculous CD/Inability to build again, as well as give the US Captain's 'rally' but set it as a passive, like the Commissar I've seen from other tune-ups.)

I'm sure that a majority of the modders here (Janne included), would say, is to really figure things out is to explore, and in my doing so I ended up breaking some things (Warnings, and big red '!'s from my fiddling) I ended up having to start from scratch multiple times in the past week. And I think that if I manage to get a handle on creating ONE custom unit, I can figure out how to tweak and work stuff out from there.
