Tournament players may find this a problem, but against a reasonable opponent you should be able to work it all out. The trick is you get to pick when in the sequence of play your reserve phase happens. I haven't come across before. Combat's kind of interesting as well. Units have 2 ratings, a combat factor and a morale rating.
Successful attacks force retreats and morale checks, and failed morale checks lead to disruption.
Disrupted units are weaker in combat and are eliminated if disrupted again. Surrounded units can surrender, disrupted units can rally. All units are therefore 2 steppers, but you're not never exactly sure how long they'll hold out. The biggest letdown is the historical background of the original rules wasn't translated. Neither was the enclosed errata page, for that matter.
