i just thought of something.
When is stress removed via a green maneuver? Snapshot might go off before that does....which would royally put a cap on this antiaction shenanigans.
Snapshot says "After an enemy ship executes a maneuver..." From the rulebook, the ship does a maneuver, checks pilot stress (adds or removes stress based on movement). Maneuver is now complete. Normally they can now do actions, however snapshot is after a maneuver so you get to do snapshot instead. So if they do a green maneuver to clear a stress, they perform the maneuver, then check pilot stress to clear the stress. Now you can declare them target of the attack, and with R3A2 they get a stress.
