Strider L8 Abilities

Just a quick clarification: On the Strider L8 abilities Snapshot and Riposte, when it says “When announcing actions”, does this mean when you reveal the actions along with the GM. Say I’m using a bow and I lay I play a Maneuver and the GM plays a Defend. Is that when I announce that I’m switching to Fient at -1D? (I believe that is the case. I’m just seeking clarification.)


Quick and to the point. I respect that. Thank you, good sir.
