What type of gas is the ABC m7A3 used for riot control?

The ABC m7A3 is specifically designed to utilize CS gas, which is a type of tear gas that causes irritation to the eyes, skin, and respiratory system. CS gas is widely used by law enforcement and military personnel for crowd control and in riot situations because it can incapacitate individuals without causing permanent harm.

While CN gas (Mace) and OC gas (commonly known as pepper spray) are also agents used for riot control, they are not the primary focus of the ABC m7A3, which is specifically optimized for the deployment of CS gas. Understanding the different types of chemical agents and their specific applications is crucial in the context of riot control, as each type of gas has unique effects and uses in various situations, but for this particular device, CS gas is the correct choice.
