Frequently Asked Questions

What is the 'fatal funnel' in tactical entry?

The 'fatal funnel' is the area immediately inside a doorway during a tactical entry. It's a critical point where operators can become bottlenecks, making them vulnerable if movement isn't rapid and coordinated. Clearing this area quickly is paramount for team safety and effectiveness.

How does the 'power step' aid in room entry?

The 'power step' is a specific footwork technique used during tactical room entry. It involves a slight lateral adjustment followed by an explosive forward step to clear the door frame efficiently and generate momentum, allowing the operator to enter the room quickly and safely.

What is the importance of speed during a tactical room entry?

Speed through the doorway is crucial in tactical room entry to prevent the creation of a 'fatal funnel'. Rapid entry allows the entire team to get inside the structure quickly, establish security, and begin clearing the space effectively before any threats can react.

What rifle setup is shown in the GBRS Group video?

The video features an AR-15 platform, likely chambered in 5.56x45mm NATO. It is equipped with a GBRS Group Hydra Mount for an elevated optic (EOTech), a Ferro Concepts Slingster, and a B5 Systems Stock, indicating a modern tactical configuration.
