Tau Rapid Fire

And because its vaguely related but often missed...

You cant shoot once under 12" even if you remained stationary (normally not important but for those 'gets hot' weapons it matters).

Nah its stupid but thats the rule. Rapid fire can shoot twice at targets up to 12" away or once over 12" and up to maximum range if it doesnt move. It doesnt say you can shoot once or twice up to 12" only that you can choose to shoot twice or not at all.

I could be persuaded otherwise though if anyone has a compelling argument against it. My plasma-guardsmen hate that stupid rule.

Uh... I didnt say you must fire twice. I said you can fire twice.

It still doesnt say you can fire once though.
