Take shadow sun attach her to a squad of firewarriors and put them behind an aegis for a 2+ cover save
It's stealth and shrouding, +3 total, so literally any cover becomes 2+. No need for an aegis.
Sure, you can put shadwosun with a FW squad, or stealths, but she's best with Crisis, I think. Give them a 2+, too, and they all can infiltrate.
