Smoke Grenade/Battlefield 2142

"Impact detonated, the SG-34 Smoke Grenade can be used as a screening, diversionary, signaling, or offensive device, dispersing a cloud of dense potassium chlorate–based smoke."

The Assault kit in Battlefield 2142 has access to the SG-34 Smoke Grenade, which is used mainly as a visual obscurant. Its effect is rather weak and short-lived, and does not protect from AI-controlled sentry guns (or bots in singleplayer).

The Northern Strike expansion pack added the CM3-N Radar Grenade, which combined the smoke effect with a single scan from an embedded infantry sonar device.
