DSII Questions for Jon..

I posted these a couple weeks ago but never got a reply...

This weekend my game group did a 30,000 point per side 
bring-n-battle. Each player had 10,000 points to spend on a Mercenary
Regiment and, Inevitably, Questions arose.

1)Do SLAM packs ignore Stealth?
2)Why are Heavy Artillery batteries costed on the same Gradient as
Medium and Light Artillery, but lack harassing fire. (maybe there
should be a price break)
 3) If you are striking multiple targets within one beaten Arty zone 
and the second Target draws a "systems out-firer" chit, does the 
previous attack stand?

Thanks!
