A gas grenade is a hand grenade designed to burn or release a gas, often an incapacitating agent.
Sleep gas grenades release sleeping gas when detonated, which cause a target to fall unconscious upon inhalation.
Big Boss and the Militaires Sans Frontières procured design specs for sleep gas grenades, during the Peace Walker Incident of 1974. Modifications were later made by the MSF's R&D Team to release a stronger dose of sleep gas when used.
Riot control grenades are used for crowd suppression.

- ―Gas Grenade description in Metal Gear 2: Solid Snake
In Metal Gear 2: Solid Snake, the CN gas grenade can be used to eliminate enemy soldiers, and has the same effect as other lethal weapons. In the original MSX2 version, it was used to determine the wind direction on the 20th floor of the Tower Building, in order to hang glide across the crevice to the north. In the re-released versions, however, the wind direction would always goes south.
Metal Gear Solid: Peace Walker
- "A non-lethal grenade that releases sleeping gas when it detonates. Anyone who inhales the gas will fall asleep within a certain amount of time. Throwing multiple grenades will increase the potency of the gas and make targets fall asleep faster.
Of course, the gas also affects the user, so make sure to throw the grenade a safe distance away."

In Metal Gear Solid: Peace Walker, design specs for sleep gas grenades can be procured in the small maintenance dock of the U.S. Missile Base in Nicaragua, during the mission to neutralize an enemy unit.
