It's not 12. It's 19.
You get there by adding an Assault Missile and a Munitions Failsafe, and promoting it to a Tala Squadron.
Run 5 of them, but promote one further to Lieutenant Blount (losing his Failsafe, of course).
You have 2 points left over for an EPT on Blount.

In other news, you either incur splash damage, or you don't spend your missile. Over 5 freakin' assaults.
I had the misfortune of Swarming against this build, and got board-wiped without dealing a single card of hull-damage to my opponent.
Is there a way to defeat this nightmare that is also effective against HSF and Swarm?
