With the introduction of different weathers on maps, some of them can cause some areas to become extremely dark. To the point of not being able to see the enemy combatant that is looking straight at you. e.g. The opera house in berlin with rainy weather, makes it almost impossible to see enemies, the only way i could tell if it was a far away enemy is i saw the shine of his belt buckle.
So my question would be, could a flaregun be added into the game? It could use the same effect as when a plane crashes into the ground and then everything around it in a small area is illuminated for like 20 seconds. The gun that could be used for it would be the kampfpistole, which is the predecessor of the sturmpisole. So technically you could just reskin the sturmpisole and make it shoot flares.
Or just give us the option to launch mortar flares or arty flares.
