Just clarifying...

During activation, as an action, you take a TL.

You declare your target

Activate R3D2 to stress yourself and the opponent

Determine attack dice and secondary weapon

Spend Target lock for torpedo attack

Clear stress

Roll dice for torps

etc.

So if you couple Hobbie w/ Flechette Torpedoes, he can double stress the enemy without even having a stress. Right?

TL for torpedoes is removed during roll attack dice.

IMHO R3D2 resolves during declare target.

So yes, you can do that.

Edit:

R3A2 reads: When you declare the target ...

Yep, looks right. Scary as hell, but right
