Oddly enough, full megapixel invisibility is more advanced than this and is INSANELY expensive compared to self colorizing materials. Optronics is using photons instead of electrons in machines which is way waaaay ahead of this time. OctoCamo (As it's called in MGS4) could be applied to anything - planes, tanks, structures... However it would be most effective with mobile units since perspective is its enemy (if it were a building, it could appear invisible from one direction, but not another).
I was an Xbox owner, what time period does MGS4 take place? Are there any other special techs from that game that can be added. ISo invisbility tech?
