What are fatal funnels in a tactical context?

In a tactical context, fatal funnels refer to congestion points that expose individuals to wider threat areas. These are specific locations where movement is restricted or channeled, leading to an increased risk of exposure to danger. For example, hallways, doorways, and stairwells can all serve as fatal funnels because they direct individuals into narrow spaces that can be easily monitored or attacked by an assailant. In high-stress situations, such as active shooter scenarios or tactical operations, understanding these areas allows law enforcement and tactical teams to better plan their movements and utilize cover effectively, minimizing their vulnerability. Recognizing fatal funnels can enhance situational awareness and aid in making strategic decisions during potential encounters with threats.
