Does a unit that has lost its last green box but still has all of its yellow boxes test at Courage -1? Yes, the rule is worded that once a unit has lost all of its green boxes it must test and is considered "in the yellow."
A question that leads to:
A note clarifying the direct path rule. Specifically, pointing out that a unit on close, if placed so that just a part of it is behind a friendly unit, allows the player to decide whether or not the unit stays behind or shifts over and moves ahead. This is a basic tactic that many folks new to the system may not intuitively grasp.
A note clarifying the fact that missile range, closest enemy, final rushing, and regular movement are, in fact, all calculated differently.
Perhaps gpman could help us out with some questions that came to his mind whilst learning the system.
BTW - excellent idea creating a FAQ page!
