[SGII] question

Just want to make sure I am doing this correctly.

I have an AT-ST with dual chin mount Heavy blasters,
basic fire control.  The blasters are 2xd12 each.

I fire them at infantry, I roll Quality and 2 d6
versus range with ranges in 12" increments.  Treat
damage as standard, the 2xd12 for each blaster
is not relevant to this situation.

So am I correct?
