Smoke grenade

From Halopedia, the Halo wiki

Smoke-producing flares are used for a variety and diversity of reasons by the UNSC. Different reasons appear to have different colors of smoke attached to them. There are a variety of smoke-producing items, few of which have been observed being in use by the UNSC.

  • Signal flare: used to alert allies of a friendly position. They utilize thick, green or white smoke.[1][2][3]
  • Smoke canister: These are used to signal for pickup after a mission, or a request for an equipment drop, or even a need for emergency evacuation. They create thick, blue or red smoke. These are also referred to as "smoke grenades."[4][5]

Production notes

Smoke canisters were used in Halo Infinite's announcement trailer at E3 2018.[6][7]
