Implacable Defence

A unit with this special rule that is arrayed in a Close Order formation, and that is equipped with and chooses to use shields, may choose not to Give Ground should it lose a round of combat.

However, if the winning side significantly outnumbers the losing side, it will overwhelm the loser. If the Unit Strength of the winning side is more than twice that of the losing side, this unit cannot use this special rule and must Give Ground as normal.
