What is signified by the terms 'tac I/ tac II'?

The terms 'tac I' and 'tac II' refer to tactical channels used in emergency communication systems. These channels are designated for on-scene operations, primarily utilized by law enforcement and emergency response teams to coordinate their efforts during incidents such as accidents, emergencies, or specific operations.

Tactical channels allow for clearer and more direct communication between units, ensuring that critical information can be shared quickly and efficiently without interference from other, more general channels. These channels operate outside of standard communication frequencies to minimize congestion and allow responders to focus on specific incidents or operations.

Understanding the role of tactical channels is vital for effective dispatch and emergency response, as they facilitate necessary coordination and enhance overall situational awareness. This is why 'tac I' and 'tac II' are significant in the context of dispatch practices.
