Why Room Clearing is a BAD IDEA
John Lovell, a former member of the 75th Ranger Regiment, explains that room clearing is often a tactical disadvantage. He details how the defender's advantage stems from having already completed the OODA loop (Observe, Orient, Decide, Act) while an intruder is just beginning. This creates a psychological bottleneck for the attacker, who must scan and identify threats, whereas the defender can leverage their position. Training focuses on narrowing this advantage gap.
