In Counter-Strike 2, which grenade creates a temporary area that extinguishes fire?

In Counter-Strike 2, the Smoke Grenade creates a temporary area that extinguishes fire.

Counter-Strike 2 introduced volumetric smoke that interacts with the environment and gameplay. A smoke grenade can put out flames from Molotov cocktails and incendiary grenades, creating a temporary way to deny fire-based area control or reopen a route.

The smoke cloud also blocks vision, although players and gunfire can interact with it in ways that differ from the older static smoke effect in Counter-Strike: Global Offensive. This makes smoke useful for both extinguishing fire and obscuring sightlines.

A flashbang blinds players, a decoy imitates weapon sounds, and an HE grenade causes explosive damage. None of those grenades creates the fire-extinguishing smoke area, which is why their names are not interchangeable.
