I was thinking today of something that could have use both inside and outside the city. Flare guns, or rather, Flare rounds and smoke rounds for grenade launchers, plus other ammo types if they don't already exist like crowd control munitions. Gasses and the like.
Flares would behave based on sightlines. It would shoot however high in the air, and if someone is in a spot that could see it, they'd get a general direction of where they see the flare shooting off from. Sort of like an AV flying overhead? They could have audible components, perhaps, or different colors for different meanings. Could also sell a single use flare launcher type of survival item for those unable to buy a whole launcher. 'You see a yellow flare far up to the Northwest'
Smoke rounds self explanatory.
Flashbangs and tear gas-type stuff, maybe.
Use the flares to guide, say, people or pilots to an area, or maybe shoot it at a person to have a chance to set them on fire.
Thoughts?
