The green canister represents the inert training units which duplicate the delivery system for live products. 

The First Defense® Inert formulation provides the same functionality and targeting properties as active product duplicating the delivery system for training purposes. The MK-4 will deliver 20-25 short bursts of OC at an effective range of 10-12 ft. This inert aerosol product utilizes a 360° stream delivery method allowing the aerosol projector to disperse OC from any angle while providing a target-specific, strong concentrated stream for greater standoff. Eye protection should be worn during any force on force training, even though this formula is eye safe.
