gas grenade

A gas grenade is a type of grenade that contains a gas in liquid form, which is released when the grenade bursts. Grenades, in general, are small bombs used at short range and can contain explosive, chemical, or gas payloads.12

Historically, grenades were used effectively in close combat and saw a resurgence during World War I due to trench warfare. Chemical and gas grenades are a major class that typically burn rather than explode. This category includes smoke, incendiary, illuminating, chemical-warfare, and tear-gas grenades. Tear-gas grenades, for instance, are used by police for riot control. Chemical weapons, in general, are agents used for their toxic effects and can be delivered via various means, including grenades.23
