I Think You'll Find...

Roll a dice. On a 1, nothing happens. On a 2-3, you can pick a new footnote to apply to your army until the end of the battle. On a 4+, you can pick a new footnote and/or a new amendment to apply to your army until the end of the battle. You cannot pick a footnote or amendment previously picked for your army. The new footnote or amendment replaces your current one.

You can carry out the 'Search for Precedent' heroic action with this unit instead of any other heroic action you can carry out with it.
