If you can imagine soldiers, fighter pilots, SF, SWAT, military trade and technical staff in the 'subtropics' clustered around an AC in the middle of the day shining their EDC and weapon lights at it to see if it works better, your imagination needs less details more reality. No offence but no military are going to burn up batteries in equipment which saves their and will often have to replace at own expense if they waste it running experiments which don't make sense.
Absolutely none taken, and likewise no disrespect meant, it was an absurd notion.
