The Supply Signal is a rare item found in Loot Crates. It is a harmless smoke grenade, which when activated and tossed will release a violet colored smoke column, calling for an Airdrop to be dropped by plane on its location.

However, the airdrop is prone to land in close vicinity rather than exactly on the location the supply signal.
