Flaregun round(s)

The Flare round is a type of ammunition in DayZ Standalone. It is used for the Flaregun to create a light source. As of 0.53, flares take up one 1×1 slot each, but can be stacked by “ejecting” each round then dragging on top of one another, up to stacks of five. When fired from the flare gun it makes a very bight area when its in the air, and when it land.
