Sorry if this has been asked already but; could you use a blue crit from a ship's anti-squadron to activate the Ion Cannon Batteries effect. The Rules Reference states that in Step 5. Resolve Damage of an attack that critical effects are are resolved and that only hit icons count as damage against squadrons. There is nothing stating that I couldn't use the Ion Cannon Batteries to discard a CommandToken from a defending Squadron (which squadrons can't have) or deal an extra damage as it has none.
Thoughts on if this would actually work?
Edit: I somehow initially read that it was defense tokens, not command tokens.
