AP-5 reads:
When you perform the coordinate action, after you choose a friendly ship and before it performs a free action, you may receive 2 stress tokens to remove 1 stress token from it.
Just out of curiosity, is the following possible? AP-5 coordinates an action to a friendly ship, takes 2 stress and removes a stress from the friendly ship. The friendly ship tries to perform a boost but can't perform it. Therefore AP-5 is free to coordinate another action or perform another action entirely. AP-5 coordinates an action with chopper to a second friendly ship, takes another 2 stress and removes a stress from the second friendly ship.
Or to top it off: AP-5 coordinates an action to a double stressed ship, takes away one stress. The friendly ship still can't perform an action because it's still stressed. Therefore AP-5 coordinates another action to the same ship, again taking off a stress. Now the friendly ship got rid off both stress, AP-5 took 4 stress and a damage from Chopper.
