In the base game an army may only move once per turn (i.e. you can't spend two dice to move the same army twice).
Is that also true of the expansion games (the Rohan and Gondor games)? I can't find anything in the FAQ or Battles of the War of the Ring Rulebook to suggest that an army can't be moved as many times as the controlling player has dice to spend. Is there something I'm missing in the rules, or can armies really move that quickly?
