I have a couple questions about Charging Assault/Fire:

1) Say I was playing with a Wookie Elite Warrior who has Charging Assault +10 & Momentum. Since you move during Charging Assault would you also get Momentum? I believe this is the case, but when I tried to do this in a game, my opponent made the argument that because Charging Assault replaces your turn, you can only do what is printed in the move and nothing else. In other words, they said that all other special abilities (Momentum, Opportunist, Jedi Hunter, etc.) don't apply to your attack. Which interpretation is correct?

2) If, hypothetically, a character had Twin Attack and Charging Assault (or Charging Fire), would they be able to make a Twin Attack after using Charging Assault? My understanding of Twin Attack is that it is considered one attack (whenever this character attacks it makes two attacks). Based on this reasoning, if Charging Assault lets you make 1 attack, and your character attacks twice whenever it attacks, this 1 attack would be a Twin Attack. Is this correct?

Thanks for the help!
