At a recent game of Warhammer Great War, one of the players suggested that there was a special rule for the Germans (in 1914) that allowed them to move faster if they were in close order.
I could not find the rule in either of the two books - was it published separately, or might he have been confusing different rule systems? of course, many of the rules are scattered throughout the books, and some details are not always easy to find.
Thanks!
