Tactic

Source Battlecry! pg. 23
Tactics are special abilities that involve you signaling your allies to perform predetermined maneuvers. To use a tactic ability, you must have one or more willing allies you have instructed beforehand during your daily preparations, called squadmates. Your squadmates must also be able to perceive your signal, either when you speak or shout it (in which case the tactic action gains the auditory trait), or by physically signaling them, typically by waving your banner (in which case it gains the visual trait). While you can use multiple tactic actions in a round, a character cannot respond to more than one tactic per round, regardless of source. You can’t Ready a tactic.

Tactics often grant actions or abilities that can be used as a free action; these can be used outside the squadmate’s turn just like reactions.
