[PUP] FLIR and Nauticomp display

[Mike & Denise]

Ron,

I was on a BFV for a few years, the original version, it did not have FLIR.
(That is unless the AN/VVS2 for the driver was FLIR, but I don't think so).
The Integrated Sight Unit was 4x/12x Thermal for night vision. In Germany,
we dealt with a lot of fog. The ISU was good until it wasn't. Meaning, in
light to medium fog, we had no issues seeing a engaging targets (I might
note here that seeing a heat signature on a tank or truck is probably
significantly different than seeing the heat signature on a boat especially
a large one. The engine is usually what shows hot.) In heavy fog, we had no
luck at all seeing targets. I spent one evening in a thick fog trying to
identify targets to see if we could reopen a range. I ended up nearly
shooting two deer with my 25mm cannon because they looked like a target.
Smoke was similar. We launched the Bradley self protection package of Mark
VI smoke grenades and had to close the range for an hour until the smoke
dissipated. All we could see with the thermal sight was the smoke grenades
themselves burning.

A brief check of FLIR systems indicates manufacturers have merged infrared
and thermal technologies in some of their systems and kind of muddied the
waters on what each is capable of.

It is my *recollection* that the Bradley Fighting Vehicle has "FLIR" that 
can see through both smoke and fog. However, the acronym might be slightly 
different. Otherwise, everything Scott says tracks with the basic FLIR 
concept which is that it sees warm things as contrasted with background 
temperature such as a person in cold water.

You just got the 44 and now you are going to morph it into a 48!? Why, John?
