So, Fire for Effect lets you use your Reaction to make a Standard Attack.
Does this supersede the rule that you can only make one Attack Action in one round? If so, does it let you exceed the weapons RoF? Additionally, can you make this attack on the same Initiative Order as your other attacks?
So, I have a bolter. I shoot with it semi-auto. Then, I snap off another shot. Is that legal?
Or, I have a lascannon. I shoot once as my regular action. Then, I shoot it again with Fire for Effect, even though its RoF is 1.
EDIT: Whoops, I clicked "publish" twice.
It supersedes general rules of how many attacks per turn you can make, just like Bolter Assault or Furious Charge would.
It would not allow you to exceed RoF. RoF is "amount of shots that can hit per attack," not per turn.
Bolter example = yes. Your action is shooting semi-auto. Your reaction is a Standard Attack. You followed the Squad Mode rules, the specifics of which supersede the general rule of one atatck per turn.
Lascannon example = yes. Your action is shooting a Standard Attack. Your reaction is a Standard Attack. You followed the Squad Mode rules, the specifics of which supersede the general rule of one atttack per turn. RoF applies to maximum shots that can hit per attack, not per turn.
If you had a plasma cannon with Recharge, for example, I don't think you could use your Reaction to fire again because you'd be recharging.
As to Initiative, I'd assume that unless you're using your Reaction defensively (against an incoming attack) then you'd be able to use it at any time in that turn before the next turn starts. Logistically that can create an order issue. For things like Bolter Assault or Furious Charge, I have the squad enter a "sub-round" where they go through the Squad Mode attack in the same initiative order as the rest of the battle, for simplicity's sake. Not necessarily a bad idea if you're at the end of a turn and use your Reactions though since Reactions refresh differently, you have a bigger area of time to use them, essentially anytime before your next action.
