Quick Reaction Groups (QRGs) are staffed with specially trained security personnel, special equipment, "King Marshall" Security Service patrol vehicles, and provide round-the-clock patrols in a number of cities in Armenia, particularly Yerevan, keeping in touch with the Control Center.

In case of any alarm, the QRGs, arriving at the scene within a few minutes, finds out the cause of the alarm, and if an incident has occurred, ensures the security of the facility, informing the law enforcement agencies about the incident. Daily patrols of protected objects are carried out on a non-fixed schedule.
