I'll chime in by pointing out we all have roughly a battalion sized unit, with some manner of supporting elements. Gunther's bat is a consolidation of the remains of his brigade's three battalion into one, mine is a bottom-up gathering of militias. If you want to have two battalions, I'm not going to stop you, but in order not to overextend I'd suggest having Sokol group around the strength of a (reinforced) battalion, with nine to twelve infantry platoons.
