11 Roles of Unarmed Security Officers in Active Assailant Incidents
3. Monitor and Communicate
Initiating armed response quickly is vital, and continuing to monitor the location of the attacker from a position of cover (such as relaying that the suspect is on the third floor of the building) can significantly reduce the time it takes armed officers to locate and engage the suspect. This is important if the attacker is no longer making noise (possibly because he is reloading a firearm). The information that security officers provide can be used by law enforcement to locate the suspect.
