For this is one piece suit of armor, we do nort need mobility upgrade I suppose (just dont know if I remember it correctly)
Scouts should use ruthenium, maybe instead of chemical or fire protection (napalm and chemical warfare are usualy not used agains a single targets...)
This are just my add to discussion, as we have some time to kill

RIG - deffinitly yes. Cameras are not enought, RIG as it is described also provides medical logs, ful scale reports etc.
Level of stress, for instance, is very important tactical info, as the system would consider how firm that point of formation is and gives a commander a signal that:
"Boys and girls on the left flank would need some morale boost, or the deffense is going to be torn appart..."
It also covers emergency medic calls and those medics should read on their display, whether it is worth of a risk or it would be a cold case...
As I read it, it would be part of the standard equipement across military units, not a matter of choice.
