Thermal Viewer

Okay, I know that IR vision and NVGs have been brought up before. SOME nvgs can see in complete darkness with an IR illuminator. How about an Thermal Viewer? The US Army uses them, I think it's the AN/PVS-8A viewer. It would allow you to see people hiding behind bushes etc. BUT because thermal viewers are pretty bulky, you could make it that u can't move will using it. Intense heat sources like grenades going off could blind you for a moment.

If I remember correctly, thermal viewers are as big as an medium video recorder (Hand Held). The point is that if you could move with it, you could see where everyone is, even if they are behind cover. By only being able to use it while standing still, it makes the gameplay easier. Maybe only two or one people per team could have an thermal viewer and if they die, someone else could pick it up?
