At first I thought they were going to be telling me they had "SRT", come to find out it's just floating security officers! Special Response Officers (SROs) who are security officers that have worked for us for a substantial amount of time and are next in line to become supervisors for our company. SROs are not permanently scheduled at any specific account but are pre-trained at all of our accounts. In the event one of the regular officers at an account calls-off for their assignment (vacation, emergency at home, sick, car breaks down, etc.), one of our SROs is sent as their replacement.
