I sent old man simon gray video of how these units work several years ago. I also did a thread on it a long time ago. There are several prototypes
with coad names but how the units work can be under stood by understanding how a video camera works. To make somthing appear invisible you need to
take 2 video cameras for a expirement. Once you have them you take camera A. and take camera a's reciver and wire it into camera b's transiver.
Then you take camera b's reciver and wire it into camera a's transiver. By doing this you can make the forground appear to be the background and
the background appear to the the foreground.
The ones devolped by the army work off of small mirror transiver units that function both as a transiver and a revicer the units orgianly were about 1
billion to develop prototypes. It has been found that you can also use plasma screen to create the same effect with less cameras but the suit will
not be as invisible.
Hope that helps.
