Thrown · Flares

A hand-tossed signal flare used to mark drop zones for the Air Freight DLC missions. Burns brightly at night and can briefly blind nearby enemies. Functional rather than combat-oriented.
The Hawk & Little Flare is a throwable item briefly appearing in Grand Theft Auto: San Andreas and Grand Theft Auto V, and available for actual use in Grand Theft Auto Online.
In the mission Interdiction, upon reaching the top of Arco del Oeste, Carl Johnson uses a flare to signal the location for the contraband helicopter. Later, in the mission A Home in the Hills, three flares are deployed by Triads on the helipad.
When looking closely at the deployed flare in "Interdiction", the model of the projectile is identical to that of a Tear Gas grenade. However, the flares seen in "A Home in the Hills" lack projectiles.
Unlike GTA Online, the Flare is still not used as an actual weapon, but rather as a mission-specific item. In The Merryweather Heist, if the freighter approach is chosen, Michael will be carrying a flare while locating a device underwater after the ship is destroyed. Flares are also used in the mission Monkey Business, when they are carried by Michael and Dave during the underwater part. Later in the same mission, one is used to signal the location for Trevor as he is coming in the helicopter.
The Flare is a small red smoke flare that emmits a bright red light. It is primarily used to mark an area for Merryweather Airstrikes.
