I'm having a real hard time finding a purpose of the Iron Wolf. He's not an Independant Character so I can't join units so if I take him in a vehicle I want to go faster such as a transport I can't actually transport any other units but his which is pointless. I can give him some decent melee capability but I can get other units that do melee just as well for cheaper. I can make him really mobile but this seems practical only for lists that have a lot of armor in it and not a 1500 point list with maybe a single land raider or a dreadnaught.
Also, I know this is a rules question but I can't seem to figure it out - does a model in terminator armor get the +1 attack for a storm bolter and power weapon? I know you do for a power weapon and pistol but since a terminator model can use a storm bolter with one hand, I just wasn't sure.
Also, if Arjac is part of a squad as an upgrade model and the rest of the squad is destroyed except for him, is he allowed to join another unit as an IC?
