Looking for thoughts on flare guns. They are fun on the 4th of July, more stable than fireworks, can be used to start fires (good or bad intent), but since I doubt I will ever call in air support or artillery I don't know if it would be worthwhile to stock some flares.
While they can be used to signal friendlies, the other people can see them too.
I have an HK EFL but the flares are hard to find. 26.5mm flares are common and are much brighter, plus you can get a white parachute illumination round in 26.5mm.
