Just want to confirm - is choosing team tactic cards considered part of the squad-building process, or is it done after? It makes a big difference as far as choosing affiliations go now that "The Initiative" is on it's way. Can the card be used to clear the 50%+ threshold for affiliations, or does your "squad" need to be at 50%+ prior to choosing team tactic cards? Page 13 of the rulebook seems pretty clear on the subject to me, but I have heard there was an additional ruling that takes precedent over this.
