Which of the following should be included in a "Mission Brief"?

Including mission objectives and route in a "Mission Brief" is essential because it provides the team with a clear understanding of their goals and the specific path they need to follow to achieve those objectives. This information establishes the operational focus and ensures that all members are aligned in their actions and decisions during the mission. By clearly outlining the mission objectives, the team can prioritize their activities, allocate resources efficiently, and assess progress, while the defined route helps in navigating the area effectively, supporting situational awareness.

While aspects such as equipment inventory, weather conditions, and team member backgrounds can be important to the overall mission planning and execution, they do not directly convey the critical operational tasks and pathway that guide the team's actions in the mission brief. Thus, mission objectives and route serve as foundational elements that drive the entire operation.
