I have read something that I don't think can be right but I can't find an exception.
On page 4 of the Rules Reference in the section on Defense Tokens one bullet point reads: " If the defender’s speed is “0,” it cannot spend defense tokens. "
On page 6 of the Rules Reference in the section on Engagement we find: " An engaged squadron cannot move. " Which essentially means they have speed 0 while engaged.
This would essentially mean that a unique squadron that is engaged (and therefore at speed 0) cannot use Defense Tokens.
Surely this is wrong, but I can't find anything in print to argue against this supposition. Hopefully one of you can tell me where it says that a speed 0 unique squadron can still use its Defense Tokens.
