The R-Series CS Gas Discharger is a standard tactical anti-personnel gas grenade, capable of discharging CS Gas (Also known as tear gas) over a defined radius. A hand-thrown device, the grenade has no effect against inorganic targets or targets equipped with sealed environment masks or rebreather Augmentations; however, against unprotected organic targets, the discharge cloud causes temporary loss of vision and a nausea reaction. Upgrades: The gas grenade is not upgradeable, but it can be turned into a very effective "gas mine" when combined with the Mark 87 Tactical Munition Mine Template.
