Players will sometimes find the movement of troops results in the tabletop becoming quite crowded, especially where several different units are engaged in hand-to-hand fighting. It is obviously important to establish which units are actually fighting, and which are close by but not engaged - perhaps merely passing by, for example.

For this reason it is an accepted convention that opposing troops are kept at least I" apart when they are not fighting. Models which would otherwise approach to within 1" of an enemy without engaging them are simply halted 1" away. Remember that units may only engage in hand-to-hand fighting by means of a charge, except in exceptional circumstances, as noted later.
