Brothers in Battle says: Bushido Virtue • Duty Battle/Open: Choose two or three of your performing Samurai: Each of them has +1F and the ability "Battle: Ranged 4 Attack" while in an army with one or more of the others.
Matsu Naomasa says: Reaction: After one of your Bushido Virtue actions targets Naomasa: Gain 2 Honor
Question: Is "choosing" Naomasa for Brothers in Battle considered "targeting" for Naomasa's reaction?
Is "choosing" Naomasa for Brothers in Battle considered "targeting" for Naomasa's reaction?
No. Targeting is explicit; the actual word "target" must appear, or it isn't targeting.
http://rules.l5r.com/CE_Glossary_T#Targeting: "The word “target” must appear as a verb or an adjective for the procedure to be considered targeting -- just “choosing” something is not targeting."
