The Strategic Response Unit handles the toughest, most extreme emergencies. They have top-notch, advanced training in bomb threats, hostage negotiations and highly dangerous criminals. The SRU is a branch of the Canadian police force. Led by Gregory Parker, the SRU team consisting of six original members uses negotiation and intuition along with its other skills to avoid taking out the bad guys. They prefer to use their intelligence but when all other hope is lost, they know that they will be required to make a quick decision and take extreme measures to diffuse a situation before it can develop into a further crisis.
