While attacking a ship, each of your [Crit] icons adds 1 damage to the damage total and you can resolve a critical effect.
You are not prevented from moving while you are engaged by only 1 squadron. A squadron with Grit is prevented from moving while engaged with multiple squadrons if at least 1 of those squadrons lacks Heavy.
You can move and attack during the Squadron Phase (in any order).
