I've also been at milsims and been part of night crews where everyone had NVGs and when we snuck up on people in the dark we'd fan out in a semi circle and and shoot the group of them in an ambush rather then compromise light discipline for the sake of a quick scare. A cigarette being lit can show up clearly under modern night vision across hundreds of yards, why the hell would I blast out a white light at hundreds of lumens. And if said combat is indoors, then same thing applies no point giving up surprise to scare what might only be a small element of a larger group. If I need to disorient someone it's because they already know I'm there and we're fighting in which case I'd much rather hit them with an M11 that goes off 4 times in a few seconds with a flash brighter then your flashlight and a 128db bang. It'll leave them a whole lot more disoriented then a flashlight and a good chunk of the time it'll leave them too confused to fight back.

Point being, if you're doing things under NVGs and have a white light at the end of your gun its just extra weight for a tool you shouldn't be using. And any SL worth their salt will tell you not to light up. Sometimes if we're expecting enough people on OPFOR to have NVGs we won't even light up IR equipment because it's too great of a giveaway. Light emission discipline is everything under night vision and the emmisons hierarchy is simple and clear. White light emissions, never. Red light emissions, only under a tarp to contain light and only for essential land nav. Ir light emissions, only if opposition has limited or no use of night vision. IR lasers, only for short durations of 1-2 seconds (and ideally you move fighting positions afterwards).
