Just bought and assembled my Core set, and now playing the "learn to play"

But i got some stupid questions, that need answers, and i figure this is the best way to do it.

1 Attacking Squadrons with a ship: on page 15 is says it uses the ships firing arc and range. My Corvette is in Medium range of a TIE fighter Squadron

a. can it attack the Tie Fighters?

b. Does it use the Anti-Squadron attack dice instead of the dice printed on the card [CR90B could have 2 blue]?

c. What range can it attack squadrons?

2. X-wing with escort

I know it is the core game, but it seems the Escort ability only works when the X-wing is engage, and they have a friendly fighter nearby that does not have Escort, correct?

1a: yes the CR90 throws 1 blue die as it's anti-squad. Blue dice for ships can attack up to Medium away

1b: yes, it needs to use anti-squad dice (die in this case) against squads

1c: depends on the die color: in this case, up to medium range since it is a blue die.

bonus: note this range doesn't apply to squads attacking. that is always range 1.

2: I'm not sure I understand the question fully but yes, a TIE Fighter is in range of both an Xwing and a Ywing. Xwings have escort so the TIE Fighter must shoot at the Xwing. If the TIE Fighter is instead engaged to 2 Xwings, it can choose either one to target.
