Check my thinking, because I got into a dispute about this during a Vassal game:

Tactician says "After you perform an attack against a ship inside your firing arc at Range 2, that ship receives one stress token."

TLT says: "Perform this attack twice. etc etc."

So if I have a Tactician and a TLT on a HWK and attack someone at Range 2 in arc, they should be getting two stress, yes? I perform the attack once, and after each time, the ship gets a stress token. Is that correct, or am I somehow misinterpreting things?

According to the FAQ it is treated as two separate attacks, so yes two stress.

yeap 2 stress

Yep, load some stress on.

Saw this put to devastating use last night, yes it is two stress

Very situational however. I would think you might only get one round while your opponent is at R2 and in arc before they get past you. And if you're in a HWK or K-Wing, getting them back into arc might be tricky.

One round is all you need really to get its value. Plus makes your ship a sort of biggs lite as it draws a lot of aggro.
