If an impetuous trooper begins their impetuous activation inside the enemy deployment zone, and can't reach an enemy trooper with their movement, what do they do? (Locally it has been suggested that they move to the back table edge and, if they reach it, turn into a queen.)
Probably worth adding to the existing Impetuous thread... http://forum.corvusbelli.com/threads/impetuous-no-double-back.37950/
