Smoke grenade



Smoke grenades are devices commonly employed by the Equalists to obscure their escape. Once thrown, the canisters quickly release a large amount of thick, opaque, green smoke.

History
When Korra and Mako tried to find Bolin at the Triple Threat Triad's headquarters, they discovered that he had been kidnapped by Equalists and attempted to pursue them as the chi blockers rode away. Two Equalists on motorcycles deployed a smoke grenade to obscure their escape. However, Korra and Mako quickly overcame the effects of the smoke and gave chase on Naga, eventually ending up fighting two Equalists head-on. The chi blockers prevailed and were approaching the two immobilized benders, when Naga gnawed through her ropes and attacked. The Equalists quickly backed down, covering their escape once more with smoke grenades.

Several days later, when Councilman Tarrlok led a task force into an underground base where chi blockers honed their skills, one of the trainees released two smoke grenades to allow himself and a woman to escape. However, Korra quickly reacted and froze the grenades with her waterbending, effectively sealing them before they could release their full contents.

Weaknesses


The smoke is harmless, and while it creates effective cover, the concealing effects do not last long. The grenade can be rendered useless by preventing it from releasing smoke, for example, by using waterbending to freeze the canister and sealing it. Being smoke grenades, the smoke can be blown away by a gust of wind, making them useless against an airbender.
