The nature of a game of Warhammer, the varied terrain it is fought over and the stability of the models themselves means that it is impossible to be absolutely accurate about the movement of troops – the odd fraction of an inch will inevitably appear or disappear as lines are neatened and models edged together. On the whole, this need not cause concern during play as it is better to keep the game flowing rather than worrying about unavoidable imprecision. Where a move is especially important or an exact measurement is critical, it is good practice to agree what you are doing with your opponent before moving any troops.
