Models in the incomplete rank must normally be kept as close to the centre as possible.
If the unit is charged in the flank, the models in the incomplete rank are moved in contact with the enemy and fight normally (Fig. 4).
If the unit is charged in the rear, some enemy models might end up not in base contact with the enemy because of the width of the incomplete rank's models (Fig. 5 shows an extreme case). In this situation, models can attack the enemies in front of them even if not physically in base-to-base contact. In reality the chargers would not have stopped one metre away from the enemy and would have moved in, finishing their charge.
