The RK-2 doesn't explode and it doesn't burn. It walks through populated areas and disperses aerosolized chemical agents from vents along its spine — slowly, continuously, while moving at a pace indistinguishable from a real dog's walking gait. The RK-2 is designed not to be noticed. Its chassis is the most convincingly canine of any platform on the market, with synthetic fur covering, realistic ear and tail articulation, and a gait algorithm that perfectly mimics a mid-sized mixed-breed dog. It even pants.

The chemical payload varies by mission. Documented loads include incapacitating agents, tracking markers that adhere to skin and clothing, mood-altering pharmaceuticals, and agents that interfere with specific cyberware models. The dispersal rate is calibrated to be below visible threshold — no fog, no smell, no indication that anything is happening. Targets breathe the agent without knowing it. The RK-2 can cover an entire neighborhood in a single patrol loop.

Ringo markets the RK-2 for 'population management research' — a phrase that means whatever the buyer needs it to mean. The most chilling documented application involved RK-2 units dispersing a Lazarus-manufactured mood suppressant through a Shelf district in the weeks before a scheduled Ringo facility expansion that required resident displacement. By the time the eviction notices arrived, the population was too chemically docile to resist.
