Here's the soldier rig. It's pretty much the same as the civilian's but with a different model attached. Most of the work that was done for this rig was either getting the armor to move right on the body when he moves, applying, skinning and copying weights over from the civilian weight source or creating his prop rifle.
Here's his rifle. I used reference from modern military rifles and futuristic-looking rifles in order to get a mix that would look near-futuresque. The trigger is controllable with attributes in the box control surrounding it.
