Overcharger Card Clarification

By apnelson123, in Star Wars: Imperial Assault

Using credits I upgraded my Imperial weapon with the Overcharger card which states "Deplete this card when you declare an attack. Remove 1 die from the target's defense pool."

Two questions:

1) Does this apply to each of my attack actions if i choose to use it twice in the same attack?

2) Is this available each time I attack?

3) If my rebel player has two turns per round, can I use it twice?

Thanks!

deplete

When a card is depleted, it is flipped facedown and cannot be used for the remainder of the mission. At the end of each mission, all depleted cards are flipped faceup.

So its goof for 1 (one) attack

And an extra free tip: try to look stuff up in the rules reference booklet

I've been going back and forth to the book so many times it's insane. It did not occur to me "Deplete" was in there. Thanks!
