Consider the following scenario in Game of Thrones Board Game:
I am playing with the green pieces.
QUESTION 1. Can I march with two units onto area C first, apply the combat, and after that decide whether or not I will march with the third unit to B? In other words, can I wait for the combat result to decide what will I do with the rest of my units in A?
QUESTION 2. If it's the case that I can't wait for the combat result, and I must declare everything at once, can I wait for the combat result to decide whether or not I will put a power token on area A?
Motivation of the questions: if possible, for optimal strategy, I would like to attack the blue player first, and depending on the result, I would decide whether or not I want to march with the third unit to B. Also, I would like to be able to decide whether or not to spend a power token on area A after seeing the combat result, because if I lose the combat my pieces would retreat to A and a power token would be unneccssary.
