Sports folk, scouts, Scandinavians living way north of the arctic circle. Red light absolutely helps, and is vital - if you don't just use your light for looking straight forward, and only needs to preserve your night vision for star gazing.
I don't know what the American scouts are up to, but i attended monthly competition hikes and races as a teen, many of which i wouldn't sleep that weekend, because the event was over night. And navigating a map at night requires light. And lights on a map straight in your face destroys your vision, so you can't orientate yourself when looking up from the map. Also, all of the events had posts (you call it that in english? a "station" on the race, where you turn up, and complete a task, before moving on?) and having to assemble and engine in the middle of the night, or sew a dress, or make condoms over the fire place to give to the chieftain, as the lore of on event had me through, that takes from 15 min to an hour in the middle of the night, with lights on the improvised tables or in your lap, can destroy any crucial night vision i needed to get going. Those 10 minutes it would take, would make the team loose our place in the leader board. When we got a little more experienced, we learned how to dedicate work and task that needed white light from those without, so a navigator could do work with redlights, while the other diffused the (fake) bomb with colour wires under the bridge we had to canoe under. To this day i'm convinced the organisers only made the wires in combinations of red, blue and a grey that blended out 100% in red light, to sort the weaker troops from the better.
