I have a few ideas I wanna run by you all in terms of technology, this is stuff actually in existance by the US Army but not going to be mass produced and distributed to combat troops until at least 2020 or later, mass produced meaning EVERY infantryman would have one.<br/><br/>Furture Land Warrior is a large scale R&D fest started by the Army in 2006 or 2007. Its pretty much a bunch of high tech gear slapped onto an infantryman to make him more modern and better equiped to deal with the modern battlefield.  It consists of 5 main parts.<br/><br/>Basically, it consists of technology allowing a regular infantryman more awareness and capability to survive and do his job extremely effectively. It has high quality communications inside the soldier helmet, personal mounted video devices in the form of monocles or simple glasses/goggles which create a HUD, including IFF trackers on friendly vehicles and likewise armed infantrymen. There are even technologies today that allow a Corpsman or medic to have a device on his/her person which allows them to remotely, from a distance, track and identify any wounds another soldier has suffered based on monitoring heart rate, blood pressure, oxygen levels and blood flow(If flow is severely limited in the leg, its possible the leg is gone, though if the food is there thats ruled out, so its possible he was shot in the leg) so when the medic arrives, he already knows exactly what is wrong with the soldier. They are even creating kevlar vests that have AED's built in to do CPR remotely.<br/><br/>Then of course they have HUD and awareness technology, as described above. Squad leaders typically have them, if you've ever played GRAW you have an extremely exaggerated version of the Furture Warrior system right there. The SL can see friendly vehicles, even satellite images of the battlefield, and friendly troops from behind buildings, and everything, all managed by satellite. Given that that is today technology, in blah blah years from NOW, its not hard to imagine said system incorporating a technology to identify anyone not with force tracking technology, civilians and such, even detecting the chemical residue on weapons and labeling them potentially hostile from a mile away or behind buildings, even under ground, etc etc...<br/><br/>Thats just what I can explain, there is shit out there that I can't even begin to put into words... they have laser defense systems building into tanks that can destroy RPGs, and even small ones on soldiers that can destroy incoming bullets, shrapnel... you name it. It more or less matters how techy you want us to be. All of the above is actual stuff, none of it is in the field en masse, but the Future Warrior system has already seen action in Afghanistan and Iraq, so its legit stuff, if a sci-fi nerds wet dream. :P<br/><br/><br/><br/>http://upload.wikimedia.org/wikipedia/en/8/83/Land_Warrior_060707.jpg (http://upload.wikimedia.org/wikipedia/en/8/83/Land_Warrior_060707.jpg)<br/><br/><br/>See there.<br/><br/>What he has is the basic HUD eye piece, communications network, and an M4A1 with what I can see are thermal imaging optics, what looks like a camera on the right side of the weapon or a flashlight, a PEQ-2 just behind the front aiming sight. I don't know what that is under the thermal optic, might be the camera or some sort of sensor, I'm not entirely certain.
