Screaming skull Ammunition // works without hitting?

[Teletomas]

 

Hi all.

I was just pondering the Tomb Kings compendium -have an upcoming match against an Ironjawz player- and fell over the Screaming Ammunition rule where you subtract 2 from bravery of any units attacked by it..

"Screaming Ammunition: A unit that is attacked by any Screaming Skulls must subtract 2 from its Bravery until the end of the next battleshock phase." 

As I am reading the wording, this works even if you don't hit anything? Ie. just by ATTACKING a unit, this debuff will take action. Am I correct in this? 

(as a sidenote, if you couple that with three tomb banshees and vampire lord on abyssal terror's command ability - opponent uses two dice for bravery tests, pick the highest- you might possibly have some fun with the poor orks)..

What do you think, am I reading this correctly? This automatically works?

Yep, SSC are awesome. You can even split fire to debuff two different units at once.

Bear in mind, though, a Ghostly Howl isn't a battleshock test, so it doesn't benefit from Supernatural Terror.
