Battlefield 1 players are familiar with the flare gun and it's not normally use to kill a person. One BF1 player though showed how he uses the flare gun to "instill fear in his enemies".
Flare Gun Normal Use
In Battlefield 1, Scouts use two types of flare guns. The Spot Flares is used to reveal hidden enemy positions especially at night. The Flash Flares on the other hand is use like a flashbang except that you hold and aim it at your enemy. The flare's heat can also inflict substantial damage.
Flare Guns Can Kill
Video presenter Willy Mammoth recently showed how he got to kill enemies using a flare gun. We can only assume that he is using the Flash Flares. It seems the flare gun's intense heat will cause the enemy's clothing to catch fire. It's interesting that see that BF1 players can make flares into lethal weapons. But if your aim is to burn your enemies, why not be a Flame Trooper instead?
Willy did admit it's hard to kill enemies using a flare gun. The appeal though is pulling of such an incredible feat. He also said that using the flare gun kill is more of a psychological effect. It's important to destroy the morale of your opponent by humiliating them.
