Per the rules:
And per the "Parts of the Activation Phase" timing chart:
So if at the start of the Activation Phase I have 1 model and my opponent has 2 models, after I take my turn and activate my one model and they have a turn and activate their one model, do I get a turn to play Team Tactics cards before they activate their 2nd model, or do I not get a turn because I have no model I could activate? If I don't get a turn, does that mean that my opponent gets 2 back-to-back turns? If so, wouldn't that break the "players alternate taking turns," part of the rules?
