What must the first two officers who enter a room always ensure?

The first two officers who enter a room during an active shooter incident must prioritize clearing the room for any possible threat. This action is critical because it ensures the safety of not only the officers but also any potential victims inside the room. By identifying and neutralizing threats immediately, they can prevent further harm and create a safer environment to assist and secure those who may be trapped.

In an active shooter scenario, time is of the essence, and a swift assessment of the room allows for quick decision-making and response to eliminate or contain the threat. This action lays the foundation for subsequent responders, who can then focus on evacuation and medical support without facing an unknown danger.

While the other options might be relevant in certain contexts—like ensuring officers are equipped for their safety or providing communication to coordinate efforts—they take a secondary role compared to the immediate imperative of ensuring the room is clear of threats in an active shooter incident. Thus, ensuring the area is safe is essential for the success of the overall response.
