Wave 5 - TACTICAL CUBE 138 - Full Assault

Full Assault's wording is different than other abilities that allow you to make additional attacks. It simply says you make choose multiple targets for your assault and that each target must be attacked with at least 2 dice.
Does this ACTUALLY give you more attacks using a Pool of dice or is it considered 1 attack? (could 1 part of the attack be canceled by Varel while the other attacks still hit their targets or would Varel save an entire fleet?)
Do those dice have to be assigned to each target before rolling?
Can a Single effect like Spock/Scan or Spending Target Lock affect all the dice or only those assigned to a specific target?
