Ah, that would be my apparent misunderstanding of force org.
Helbrute is in there because i already have the model. I hadn't really looked into taking any tanks, do you think the shooty platform is well taken care of by the trio of oblits? If so, then i could probably change the helbrute's role entirely.
Ya, terminators would be a deep striking unit to harass. Basically a similar role as the raptors but less mobile (so DS instead).
