As the CRB states "Attacks are usually made by units as part of an attack action but can be made as part of another rule. A unit may make multiple attacks a turn but can only perform one attack action per turn, regardless of whether the attack action is a free action."
How does the interaction with key words like Standby and relentless interact?
A) Boba Gets his independent Standby it is Triggered he attacks, is he now able to attack on his activation? or Cassian attacks on his activation and takes standby from Crack Shot can he attack if the standby is triggered
B)There is no try A unit attacks during it's activation, Yoda then uses guidance on that unit they perform a move action they have relentless can they now attack?
