San Tan Gear's Rapid Deployment Shield (RDS) was designed and patented by a police officer for police officers. It allows patrol officers to carry a ballistic Level IIIA shield in the front passenger seat of their patrol car for quick access and deployment. It deploys in less than a second and provides more coverage than the average hard shield, according to the company. You can also mount the RDS on motorcycles and bicycles. You can wear it like a backpack for hands-free protection and can be put on a car door for high-risk stops.
