I had a simple idea for including flares in the game. How it could work: when deployed, it marks a blip to all nearby team members signaling for help or assistance. It could look like a standard flare that you twist and it sparks red and you can throw or drop it, or use a flare gun. Could be very useful to signal choppers to give air support, call tanks, or just reinforcements in general. Also just looks cool lol.
