Which of the following refers to actions taken to achieve the strategies based on the size-up of the incident, objectives, strategic priorities, and the mode of attack selected?

The term that refers to actions taken to achieve the strategies based on the size-up of the incident, objectives, strategic priorities, and the mode of attack selected is tactics. Tactics encompass the specific techniques and methods that personnel implement to execute the overarching strategies.

Strategies provide a broad plan for addressing the incident, while tactics are the specific actions taken within that plan to achieve the desired outcomes. For example, if the strategy is to contain a fire, the tactics may include specific methods like using specific equipment or focusing on certain areas first based on the assessment of the situation.

In the context of emergency services, understanding the distinction between these terms is crucial for effective incident management. While objectives outline the goals that need to be achieved and operations may describe all activities as part of the response, it is the tactics that translate the strategic vision into concrete actions on the ground. This makes tactics a vital component in the effective response to any incident.
