This thread is not asking if a devastator should be allowed to carry 2 heavy weapons. I'm purely asking from a mechanical and weight perspective would a devastator be able to carry 2 heavy weapons, just assuming he had some way of storing both on his person.
An average DW Space Marine starts with a SB of 10 in his power armour. Would that give him enough strength to lug around 2 Heavy bolters and his backpack ammo supply and whatever spare clips and other equipment is standard issue? What if the player put him up to a combined SB of 12? Has anyone else had a look at it and worked it all out?
