"GAME OVER, MAN. GAME OVER!"
Unwashed and somewhat slightly dazed...
It´s a teleport homer. As I remember, you reroll scatter dice, or something else beneficial, when deepstriking/teleporting with terminators within X distance.
Had the time to look in the SM codex...
If you deepstrike/teleport with terminators within 6 inches of the teleport homer, you don´t scatter at all.
