M12 CCPG Grenade

The M12 Crowd Control Poison Gas Grenade (Abbreviated M12 CCPG Grenade), also known as the Gas Grenade, shortened Gas Cans or simply Gas 'Nade, is a COH-issued Grenade that functions in a manner very similar to contemporary smoke grenades.

Design Details
The CCPG consists of a sheet steel cylinder with four emission holes on top and one on the bottom to allow smoke release when the grenade is ignited, with two glass panels on the side. The filler consists of 450 to 550 grams of Flurochlorine Phosphate, a mixture between Sarin and Chlorine gas that provides it with a green coloring.

The gas itself is mildly dense, and is capable of hanging in the air for more than a full minute. It's also very thick, with clever use allowing people to hide in the clouds, picking people off one by one.

Effects
Upon being thrown, the emission holes release the toxic payload, the gas flowing outward at a rapid pace. A good throw is can possible conk someone over the head and knock them unconscious, stopping them from running from what comes next.

The gas itself, like some other nerve agents, attacks the nervous system by blocking off synapses, preventing neurotransmitters from jumping between nerves. This makes it more difficult for the body to provide instructions to the rest of itself, slowly paralyzing the target. This leaves them vulnerable to the more lethal side of the gas.

Flurochlorine Phosphate makes it's way into the lungs if the target is unable to escape from the cloud in time. Symptoms of exposure include tightness in the chest, burning sensations, especially around the torso, sinus irritation, and acute wheezing. More serious symptoms include internal bleeding within the lungs, severe eye irritation, and pulmonary fibrosis.

Exposure to small amounts of Flurochlorine Phosphate can cause asthma-like symptoms. However, as long as the subject is not exposed to any more of the gas, recovery is definitive.

Grenade Spam
As with all throwables, the M12 is capable of being thrown in quick succession with other grenades, either from the user or squad members.

In the context of the M12, Grenade Spamming allows more ground to be covered in it's contents, with some paratroopers throwing them while in the air to release the gas from above. Unfortunately, this has the drawback of causing friendly fire if not properly communicated.

Stealth Smoke
The gas inside the M12 is incredibly dense, and is tough to see in. This allows for multiple canisters to be detonated at once, creating a deadly cloud that not only kills those who charge into it, but enshrouds those with the right protective equipment. This tactic is usually coordinated through the codewords "Golf Sierra", 'Green Storm.'
