Are you just stupid? I'd GLADLY trade an extra carried MRE for this thing to be able to pinpoint the badguy sniper throwing lead my way.
Google the term "soldiers carry weight", then tell me that I'm stupid.
The results of the search will help to explain the weight aspect of my questioning of this new technologie's efficacy.
There are many, many tools, gadgets, etc that soldiers could carry that would protect them, but you'd need to be superman to carry them all.
