If a unit has this special rule then supporting attacks can be made by an extra rank than normal on a turn in which the unit did not charge. Accordingly, a unit with this special rule can normally make supporting attacks with two ranks. Remember that supporting attacks cannot be made to the side or rear, but only to the front.

A horde with this rule will make supporting attacks with three ranks!

Unlike most special rules, the effects of multiple Fight In Extra Ranks special rules are cumulative.
