I am by no means new to the game or really to space marines in general, but I know that BT work just... a tad bit differently than their counterparts.
I was thinking of making a list using small units with assault/heavy weapons. I was wondering if it would be better to take these units with a lascannon razorback to create more of an anti-tank threat, (after the razor is blown up, you still have the dudes inside,) or if it's better to just stick to a rhino. I know razorbacks are expensive in the codex, but I wasn't sure what people have more success with.
Any ideas would be great.
