[R-390] Need EAC-sized nameplate, will trade?

Al,

I love your "technical" tongue in cheek response!  [LOL!]

The serious side, have folks ever operated passive infrared 
detectors/night vision equipment?  Do you know that glass *blocks* the 
path of infrared?

I used both AN/PAS-7 and AN/PAS-10 passive systems.  If you had two 
people standing side by side, one wearing glasses with glass lenses, you 
could tell who was wearing the glasses immediately.  Their eyes were 
essentially black.

Those systems were very enlightening.  They were initially meant to 
detect non-metallic mines.  They ended up being used for other uses.  
The outfit that I had been assigned for a bit of my military career used 
them for finding potential problems in a power distribution system.

Bad connections lit up like a bright flame. (Well, almost.)  We even 
tried to see the difference between the original cotton fatigue uniform, 
the old Viet Nam era Jungle fatigues, AND the new BDUs, or "Battle Dress 
Uniform", the first real official across the service camouflage uniform.

The BDUs were clearly inferior!  They retained so much body heat that 
whomever was wearing them showed up *significanyly* brighter!  *We* all 
laughed like crazy!  These BDUs were "supposed" to be treated to limit 
the IR issue.
