I was looking at my rulebook the other day and I noticed that a Techmarine can take a heavy bolter through the signature Wargear option and I was just wondering is it better to take a techmarine w/ a heavy bolter because of the additional skills and servo-arm that comes included. I think that it would be cool to have a techmarine w/ a heavy bolter but I am also not sure If the techmarine can take the backpack ammunition. There seems to be nothing about not being able to have an aditional ammo supply on top of the techmarine back-pack. This also is a question of multiple backpacks on a single person, like a jump pack and a ammo supply
Just want to get some opinions
