SRT Call Sign Abbreviation

Special Response Team

Special Response Team (SRT) is a tactical unit designation commonly used by law enforcement and military organizations, often serving as a call sign in radio communications and operations. These teams are highly trained to respond to high-risk situations such as hostage rescues, armed standoffs, counter-terrorism missions, or raids involving dangerous suspects. The SRT call sign identifies the unit quickly and clearly in real-time coordination between various law enforcement branches, ensuring swift and structured communication during critical missions.

In many countries, SRT units function similarly to SWAT teams, but their naming can vary depending on agency structure or regional terminology. As a call sign, “SRT” is used not only in verbal radio traffic but also in planning documents, mission briefings, and tactical command centers to represent the specialized unit. Their presence often indicates that a situation requires heightened security protocols and expert intervention.
