What is the name of the flare gun in PUBG that calls a care package?

The PUBG flare gun that calls in a care package is the Flare Gun.

The item is a specialized signal weapon rather than a conventional firearm. When fired into the sky in the appropriate circumstances, its flare signals an aircraft, which drops a special loot package. That crate typically contains powerful or otherwise uncommon equipment, making the shot valuable but also revealing the player's position.

The flare gun is easy to confuse with a signal pistol because both names describe a device that launches a bright flare. However, “Flare Gun” is PUBG's standard in-game item name. A smoke grenade or smoke-producing weapon can conceal a player or crate, but it does not summon the aircraft.

The care package mechanic is central to PUBG's risk-and-reward design. Rare equipment attracts players toward the same visible drop, often turning the landing area into a dangerous ambush site. The flare gun therefore provides access to better gear while creating a major tactical trade-off.
