From what I've seen, (Canadian Army), general issue is still the angle head 2 D cell light. Some units I've been to have LPO (local purchase order) either AA Maglights or a cheap Maglight clone. Keep in mind that I'm not special forces or anything like that, I'm a Weapons Technician, so my scope is rather limited.
What's wrong with just fighting in the day? Perhaps if armies got a decent nights sleep they'd be less inclined to fight each other. Arguments can be easier to resolve if you sleep on it and come back refreshed...
Size15s you silly goose!!! They need flashlights to go out and pickup the casualties and all the body parts strewn about the battlefield so they have a nice clean place to fight the next day!!!!! They also need the flashlights to clean weapons and pick the intestines out of the tank treads!!! If you dont get that crap out right away they get all rusty
Not sure if I like the slant this thread is taking in the last 2 'contributions'... anyway, if you want to really upset soldiers in a dark 'situation', turning on any type of a flashlight is a pretty good way to do it.
I served in the U.S. Navy. There was no standard issue flashlight...you could use whatever brand of light you wanted, because you bought your own. The bridge crews used (and continue to use) red filters on their flashlights to preserve night vision, which is essential at sea. These bridge lights however are typically low powered, because they don't need to illuminate much of anything more than ten feet distant.
At night while at sea we rigorously enforced the "no lights on deck" rule, including prohibiting matches and lighters to fire up a smoke (on the antiquated theory that any flash of illumination, however dim, might give your position away to the enemy...or so the WWII era thinking went).
Inside the ship, there was no shortage of illumination, and nobody gave it much thought, unless they worked in one of the main engineering spaces. (Lots of good reasons to have a reliable flashlight down there.)
