Actually, I know that R1 doesn't give you an extra red die, but does attack at R3 give the defender another green die?

Also, shooting through an asteroid with a Secondary still gives an extra green die right?

(Insert grumbling about how hard it is to remember the rules in this game)

With Secondary Weapon Attacks, there is NO range modifier.

The only bonus dice you get are if the shot is obstructed.

So, pages 10-11 in the core rule book are where you find the answer here. Under the 'Roll Attack Dice' section we find this text:

• Also, if he is targeting a ship at Range 1 with his primary weapon, he rolls 1 additional attack die.

There is similar text under Roll Defense Dice about Range 3. It took me a while to find this reference too. Good luck.

The last line on page 10, and the very last page at the bottom. I've missed it too for a while and didn't really notice when opponents were rolling an extra die against secondaries at R3. Gonna watch more carefully now.
