Drones are used to assess buildings or environments before officers enter, particularly in high-risk situations such as raids or searches. This application involves gathering information about the layout, occupants, and potential threats within a structure.

The reason drones are used for pre-entry assessment is their ability to provide detailed intelligence without direct exposure. Small drones can even be deployed indoors, navigating through tight spaces and transmitting live video feeds. This allows officers to understand the environment before taking action.

The results of using drones for pre-entry assessment include improved safety and operational effectiveness. Officers can plan their approach more carefully, reducing the likelihood of surprises or errors. This leads to more controlled and successful operations. Overall, drones enhance preparedness and decision-making.
